Regression Analysis: Real Estatee Sales Prices and Distance to City
This regression analysis seeks to answer the question of how the sales price of Real Estate listed houses changes with the distance from the city. Does the sales price increase or decrease as the distance from the city increases or is there a relationship between the variables at all? Given the attraction of city living and the general trends of suburban house prices, it appears reasonable to hypothesize that the sales price of the houses will decrease as the location of the house moves further away from the city.
Raw Data from Real Estate Listings:
Key: Distance is measured in miles and Sales Price in thousands of dollars.
The regression line, which best illustrates the relationship between the two variables of the data set, takes the equation ? = b + ax. This equation is based on the least squares…
Its name tells us the criterion used to select the best fitting line, namely that the sum of the squares of the residuals should be least. In other words, the least squares regression equation is the line for which the sum of squared residuals is a minimum (Dallal, 2008).
Multiple regression - the general purpose of multiple is to learn more about the relationship between several independent variables and a dependent variable. For example, a real estate agent might record for each listing the size of the house in square feet, the number of bedrooms, the average income in the respective neighborhood, and a subjective rating of appeal of the house. As soon as this information is compiled for different houses it would be exciting to see whether these measures relate to the price for which a house is sold.
One good example for a simple linear regression analysis can…
egression Analysis and Business
ules of thumb, instinct, convention, and simple financial analysis are frequently no longer adequate for addressing such common decisions found in business such as make-versus-buy, facility site selection, and process redesign. Generally, the forces of competition are commanding a need for more efficient decision making at all levels in companies. "Decision analysts provide quantitative support for the decision-makers in all areas including engineers, analysts in planning offices and public agencies, project management consultants, manufacturing process planners, financial and economic analysts and experts supporting medical and technological diagnosis"(Tools for Decision Analysis: Analysis of isky Decisions, 2012).
Modeling for decision making comprises two distinct entities, one is the decision-maker and the other is the model-builder who is known as the analyst. The function of the analyst is to help the decision-maker in their decision-making process. Consequently, the analyst must be outfitted with more than a set of analytical…

It has even moved into the legal and political realms, which focus on its ability to forecast information based on similar or manipulated environmental conditions (Sykes, 2012). It is often used in quantitative research methodologies, but also conserve as a way to test for reliability in mixed methods and qualitative studies using triangulation, or more than one method to prove the same results hold true (Dizikes, 2010). In this, the research suggests that "the investigator assembles data on the underlying variables of interest and employees regression to estimate the quantitative effect of the casual variables upon the variable that they influence" (Sykes, 2012). The type of regression used in any particular situation depends on the number of variables. Simple linear regression focuses on one dependent and one independent variable. From there, more complicated forms of aggression include a greater number of independent variables, like that of multiple regression, which is…

Definition of egression
egression can be defined as a multipurpose and dominant arithmetical technique which is utilized to concurrently form the outcomes of numerous independent variables on one single dependent variable (for example, Cohen & Cohen, 1983; Fox, 1997; Pedhazur, 1997). The instantaneous assessment of independent variables is what makes it feasible or easier to better comprehend, calculate, and clarify a dependent variable; to guess their independent and collective effects; to discard unauthentic effects; to resolve more precisely the course and force of their outcomes; and to manage the likelihood of Type I errors.
Over the years, there have been many analysis made and researches done on the relationship of retirement and the incentives given i.e. pensions and social security provided.

Table 3: Predicting Elasticities of Variables
From the analysis completed in Table 3, the elasticity of each variable can be easily seen. As one would expect, the greater the variability in a given variable the higher the elasticity, especially when the variables either measure purchasing power as pi does directly or how the variables stock, and index of consumer sentiment also are shown as a result of their large variances. Taking a step back from the statistical analysis and thinking logically about this, elasticity would be defined by the level of car stocks or inventories on hand, customer attitudes and behaviors and the amount of money they had to spend. These three variables delivered a 75% R2 correlation coefficient. Elasticity is a function of price and demand so these series of relationships make sense.
The first step in completing a forecast is to define the confidence intervals. Both 90%…
In this study, these variables are considered protective factors. In the third step, childhood SES would be entered. On the fourth step, childhood maltreatment would be entered. The results of the analysis would determine to what extent each of these additional steps adds to the ability to explain the variance in resilience scores. While all of these variables may ultimately be correlated with resilience, either positively or negatively, not all of these variables will continue to "add" something to our ability to predict resilience after the contribution of other variables have been allowed for first.

It includes a way to track bidirectional changes focused on the individual who operates within the two cultural environments. Methods of data reduction have been incorporated in order to develop a psychometrically strong tool. Indexes to validate the results are included in the process as well. As a part of the BAS, scales are used to measure the various areas of acculturation rather than examining items based on the cultural dimension. The working of the scale requires using a wide range of behaviors to be used in the study and generating items in order to display the Hispanic and non-Hispanic domain under consideration. A study conducted in San Francisco, California, using this approach presented different results. Multiple subscales were used along with the regular scales. Alpha coefficients were calculated for the different subscale. All of them were pretty consistent. Validation was performed by measuring them against standards established by researchers…

Workplace egression Analysis
Give an example from your workplace regarding how regression analysis could be used by your leadership to analyze one or multiple outcomes that occur because of what your agency does. Indicate the dependent variable and at least two independent variables
To begin with, regression analysis is defined as the relationship between variables. referring to the example under consideration, the management in the workplace can use regression analysis to analyze the relationship of the tips received in the various servings compared to the corresponding amount of the bill. The dependent variable is the focus of the analysis. On the other hand, the independent variable is the 'variable that influences value of the dependent variables'. In particular, the management can use regression analysis to evaluate the impact of pricing on the behavior (tips offered) of consumers. For example, the management of the workplace can consider altering the prices on…

In short, it's the veteran employees, who seem to not be using their vacation time, that are creating the perceived problem.
By taking a regression that analyzes length of tenure vs. vacation time taken in the most recently completed calendar year (2005), we can see if employees are taking more time off as they accrue more vacation days. Our hypothesis is that they are not and that there will be no correlation between length of tenure and time off taken.
The main statistic we will analyze is the coefficient of determination. According to Aczel and Sounderpandian, the coefficient of determination measures the strength of the regression relationship on a scale of zero to 1; the closer the figure is to 1, the stronger the relationship (p.457). As Aczel and Sounderpandian indicate, it is difficult to state definitively how close to 1 our coefficient of determination must be before we declare…

egression vs. correlation?
Correlation is used to test whether two variables covary, the strength of the relationship, and the direction of the association. A correlation calculation will generate a P-value and a correlation coefficient (r). By comparison, regression will generate the slope and intercept for a best-fit line that can be used to predict unknown values for the dependent variable.

Predictions and Hypothesis Testing
What benefit does a variable provide when developing and examining models?
Statistics can be used to describe a phenomenon or conduct hypothesis testing, but statistics can also used to predict outcomes (Hanneman, Kposowa, & iddle, 2012, p. 7). To enable predictions to be made, variables are required in the statistical model. Variables allow researchers to model the mathematical relationship between two or more phenomenon. For example, the relationship between tree circumference and the number of leaves could be described by the two variables girth and leaves. This relationship may or may not be causal, but it could be correlational. If a causal relationship is suspected, then maybe reducing the number of leaves inhibits expansion of tree girth. In this case, leaves would be the independent variable and girth the dependent variable. If the model is valid, then the tree girth could be predicted for…

Correlation & Regression
A fifth grade science teacher wants to know if there is a relationship between final exam scores and overall coursepoints after adjusting for a quiz score.
In order to determine whether there was a significant relationship between overall coursepoints and final exam scores, after controlling for quiz scores, a hierarchical regression was run. All assumptions were assessed using SPSS. There was independences of residuals, as assessed by a Durbin-Watson statistic of 1.08. An examination of various scatterplots indicated a general linear relationship between variables of interest, although perfect linearity was not observed.

The commentary of the article begins with the subject of the research in the article: Organizational Politics within Academic Departments. This subject is valid of research as it is a factor of which many students are unaware, yet are apart of and by which they are affected. Uninformed views or stereotypes of academia may not include the order of politics evident among faculty and staff within each department, yet they exist. Therefore the first piece of criticism is to validate the subject matter of the study. Furthermore, the authors argue for the importance of their study as there is little research in the area, for reasons that some of which are obvious and self evident.
The specific behavioral focus for the article is conflict. The authors wish to understand the nature of conflict within organizations and the impact conflict has upon perceptions.…

economic analysis of the operating cost that are incurred in the running of a metro station. The paper also reveals the variables that are tied to the cost efficiency of the whole process of running a metro station. The cost of operating the stations is however grouped under the semi-fixed costs that are involved. This is because these costs do not vary proportionately with the output of the metro business. This paper seeks to shed light on some of the main factors that affect these costs. Empirical analysis reveals that very strong system specific factors influences costs but it is worth mentioning that there are other station specific details that also influences the costs. These include the number of platforms in the station, the length of the passageways, the interchange demand, availability of toilet facilities etc.We also discover that presence of air-conditioning has a great effect in the propulsion of…

For example, children whose last names end with a vowel may have a statistically higher chance of manifesting type II diabetes. The reasons for this might be the poverty and discrimination faced by many Latinos, the letters of whose names more often end with a vowel than other ethnicities. Poverty often leads to a poorer diet, less access to places to exercise safely, less access to healthcare, and a lack of opportunities to become educated about how to live a healthy lifestyle. It is poverty that is the causative factor to the child's ill health, however, not the child's name, and changing the child's name will not affect the outbreak of type II diabetes in the Latino community.

Correlation and regression are two important test statistics that are utilized in a study that focuses on understanding the relationship between two variables and/or the effect of one variable on another. In correlation statistics, there are two variables that are related to each other whereas in regression, and explanatory variable and a response variable are utilized ("Introduction to Correlation and egression Analysis," 2013). Generally, the main aim of correlation statistics is to examine whether two measurement variables co differ and determine the strength of the link between variables. On the contrary, regression statistics focuses on expressing the relationship between two measurement variables using an equation. As a result, of the difference in focus, correlation statistics and regression statistics are suitable for different circumstances.

1. If I were designing my research study in the field of psychology, I would most likely use a t-test as the method of data analysis. A t-test is best used when the researcher wants to determine deviations from a normal distribution curve. If there are one or more normal distributions (bell curves), t he researcher can compare the two groups using the t-test method. The variances do not need to be known to perform a t-test either, which is another reason why I would select this method of data analysis in my particular research question. Furthermore, the researcher can use the t-test to measure the differences between two populations regardless of how small or large the sample size. The t-test, also known as the student t-test, is one of the best methods applied to studies using a small sample size. If my research were to progress to where I…

knowledge management system would be beneficial in helping the SH administration with the patient data. This system is important because solving problems and making ideal resolutions on health care is heavily reliant on admission to knowledge. In today's progressively difficult environment, it quickly turns out to be vital for healthcare organizations to successfully achieve both internal knowledge and externally produced knowledge, so as to provide the best likely health care, attain operational superiority, and nurture innovations.
This would offer the best solution for the problem that SH is having for the reason that it assists with managerial competencies. When individuals in an organization experience information overload or lack the knowledge needed for decision-making, such as in the case of the incorrect prescriptions, adverse drug reactions, identical or needless lab tests, and misdiagnosis by the doctors, they become chaotic (Ashton, 2009).

Behavioral Finance and Analysis of American Financial Crisis
Financial theories are the cornerstone of the modern corporate world. They lay the foundation for most tools used in areas like asset pricing and investment banking. Most theoretical concepts like general equilibrium analysis and information economics are planted in the field of microeconomics. There are several different financial theories based on both consumer behavior, as well as how they impact decisions made by financial managers.
One financial theory that many business managers use is The Modern Portfolio Theory,
or MPT. It suggests how investors use diversification to enhance their portfolios, as well as how to price an asset based on the risk, in relation to the market as a whole. Modern portfolio theory displays the return of an asset as a variable, and the portfolio as a combination of all of the assets. The return of a portfolio is also a random…

As a brand manager for Coca-Cola, you are not happy about the fact that sales of Coca-Cola lag behind Pepsi, your major competitor, in the store. Can you explain why this happens? Also, can you recommend how to stimulate sales in store 4 by marketing more effectively? It would be useful to provide some numerical…
However, their measurable test gains may be less than students who do not have such challenges. Quality of instruction is also an issue: perhaps good instructors and smaller class size is best, but what is 'better' -- an average teacher with a small class or a good teacher with a large class? Baker suggests the former scenario is superior, given that smaller class sizes can increase the need for teachers -- good or bad -- leaving many students in the hands of less competent teachers. However, at some threshold class management becomes impossible, even for a good teacher, and the line is difficult to draw. Benefits may be different based upon student's gender, preparation level of the student, social class, and also the preparation level of the teacher. More experienced teachers may be better able to cope with larger classes, and also more adept at using smaller class size to…
The benefits of small class sizes may be cumulative, even if the overall, measured year-to-year effects are small. That would explain such problems as the discrepancies between different grade levels in measured effects of class sizes. But Baker sees such shifts as based on micro rather than macro concerns "the increase in test scores is offset by other test score fluctuations that occur between enrollments of 20 and 25. The positive ratio for third grade students (rather than negative as for second graders) is likely due to the fact that increases in test scores to the right of enrollment threshold are smaller for third than for second graders and, on the average, are offset by other fluctuations" (Baker 2009, p.13).
Even in light of her research hypothesis and skeptical conclusions Baker admits there are some indications that class size has a demonstrable effect upon student achievement. "Findings of school non-participation and creation of enrollment cutoffs [merely] demonstrate the unanticipated consequences that a class-size reduction program based on financial incentives can create, and should be taken into account when designing future class-size reduction policies" (Baker 2009, p. 5; 3). Baker's research highlights a number of questionable policies of California school districts, such as shuttling excess students to overcrowded districts. It is arguable that given the population and financial challenges of California at this time, mandatory class limitations may not be feasible, because the policies they spark to meet compliance are worse than higher levels of enrollment. It is also arguable, based on Baker's research that because of districts' methods of achieving such benchmarks are often underhanded that the class size limits are not serving the populations the programs were designed to help. But that does not mean that class size reduction is not a laudable aim. At very least, the fact that larger class sizes may cause problems for some students should be more fully explored on a qualitative rather than a purely quantitative level, given the generalized categories of Baker's research, which only takes into consideration socioeconomic categorizations.
Baker admits that previous literature indicates that small class size has been supported for some children: it is possible to hypothesize that for ESL learners and students with learning disabilities, large classrooms do not serve their needs, and the poor and disadvantaged may get 'lost' in large districts. The parts of Baker's research indicating that the overall effect of class reduction is not as large as one might expect on a general level often point to a failure of implementation, rather than a failure of class sizes to deliver upon their original pedagogical promises. Analysis of the benefits of class sizes for specific populations is still required, given the differentiation that exists in any school district and California in particular. The degree to which school districts can enforce smaller class sizes without busing 'overflows' of students elsewhere must also be examined, to see if class size reduction benefits students if it is done fairly.
Genome-Wide Association Study for OCD Complications
The OCD (Obsessive -- compulsive disorder) is referred as repetitive behaviors and thoughts experienced by individuals. (Visscher, Brown, McCarthy, et al. (2012). Typically, the genes' characteristics of twins and families have revealed that the OCD has the feature of multifactorial familial condition involving both environmental and polygenic factors. (Moran, 2013). Genetic studies have revealed that the interaction of the glutamatergic, serotonergic, and dopaminergic systems and genes affecting them play a crucial role in functioning of the circuit. (Yang, Lee, Goddard, Mand et al. 2011). Meanwhile, the environmental factors that include psychological trauma, adverse perinatal effects and neurological trauma may modify the risk genes, which can consequently manifest the compulsive-obsessive behaviors. (Visscher, Brown, McCarthy et al. 2012). The OCD is a frequent and, relative common debilitating neuropsychiatric disorder affecting 2% of the U.S. population. (Arnold, Sicard, Burroughs, et al. (2006). Typically, the OCD is obsessions…

Objective of this paper is to use the statistical test to investigate whether the middle income earners in developing countries are capable of becoming home owners. The paper uses Nigeria as a case study. Unlike the developed countries such as the United States and United Kingdom where middle income earners can become house owners, however, the issues are different in developing countries because various factors prevent middle income earners from purchasing housing units compared to middle income earners in developing countries. Typically, a level of income plays a critical role in homeownership. While different governments in developing countries have implemented various policies in assisting people to become homeowners, nevertheless, factors such as corruption, inflation, and poor implementations have made the policy non-realizable. In Sub-Sahara African countries, nearly 62% of people live in slums, and per capital income of most developing countries are less than…

Illegal Corporate Activities
Clinard's publication concerns corporate violations of stipulated laws by 582 public corporations in the United States of America. In addition, the extent and nature as well as the economic settings the violations occurred are also looked at. The study used data from the firms' sales to calculate their levels of diversification and levels of concentration among other variables. In this paper, the publication in scrutiny used sources of data though they never gave in-depth information on all violations; this makes this analysis lean on one side and may not give the actual results.
Descriptive statistics is used here to summarize the study sample as well as the observations that have been made. The main summary used is quantitative form of the data. From the data outlined in the first codebook, the five-year mean for corporate sales is 99. This is the logged value for the…

The idea behind using a regression model for forecast sales for cold beverages next year is to help the company make a better decision about that industry. The way this is done is to test all the possible influences on cold beverage demand, and apply the results. There are two different approaches we can take -- the simple approach and the complex approach. Which approach is better depends on what the decision we are making is. Obviously there are differences between the amount of time, effort and most importantly money that go into the two approaches.
The simple approach would be useful here if the decision is simply yes/no, should we enter the cold beverage market? In that case, precise demand statistics are probably not required. We can use next year's sales as the dependent variable, and then have a handful of independent variables for the past several years…

environmental, social and governance (ESG) performance and financial performance of companies
Investors are increasingly recognizing the fact that ESG (environmental, social, corporate governance) elements can substantially affect companies' security rates and financial performance. The aforementioned components' contribution to financial markets has been growing with the rise in number of ESG opportunities and risks within the contemporary international economy. Timely and improved organizational policy-related data access and the effect of organizational policy on communities have made it considerably convenient for customers to express their dissatisfaction by simply quitting a brand. When international brands' images are sullied by ESG-related problems, the resultant instantaneous backlash has the capacity of abruptly and negatively impacting income and demand (Eccles, Ioannou & Serafeim, 2014).
Organizations having a poor reputation when it comes to ESG related matters are vulnerable to monetary risks, including a very genuine threat of facing lawsuits in the future, greater remediation and regulatory…
Training Needs Analysis Practices for Managers: A Study of Saudi Arabia Private Firms
Training needs analysis (TNA) is defined by Mabey and Salman (1995:158) as a "process of collecting data which allows an organization to identify and compare its actual level with its desired level of performance." The authors also indicate that this performance could be interpreted as meaning the competencies and attitude necessary for the staff to do the job effectively. Moreover, Armstrong (1996:536) states that "training needs assessment is partly concerned with finding the gap between what is happening and what should happen.. This is what has to be filled by training ." Figure (1.1) depicts this gap.

Unit of Analysis
A unit of analysis constitutes an object of study in research undertakings (Cole, 2018). Definition and bounding of the case may prove challenging since a number of variables and points of interest overlap and intersect within cases researches. Development of research questions, propositions for case selection, focus identification, and boundary refining has been recommended for effective establishment of the aforementioned components in the study design. Case bounding proves crucial when it comes to information acquisition and analysis management, focusing, and framing. This entails selectiveness and specificity in the identification of case parameters such as respondents, process and location, in addition to the establishment of a timeframe for investigation of the case. To be more specific, units of analyses (UoIs) are decided by research questions (Merriam, 2009; Stake, 2006; Yin, 2014). Consider, for instance, Francis, Anderson and Stokes’ 1999 research “City Markets as a Unit of Analysis in…

stock market and the Banks promote economic growth and it provides a critique of their functions in transitional economies. Every country depends on its economy for its growth. For a country to be stable it has to be stable in terms of its economy. Bank and stock market contribute to a great extent to the economy growth of every country where it provides firms with opportunity to get funds thus encouraging more investment from the firms. At the same time they give information on the ways resources should be allocated. The development of a financially sound, market-oriented banking system is always considered to be fundamental to a flourishing transition. Arguably, it is important to macroeconomic stability and to positive long-term growth prospects. As documented, bank intermediation in transition economies continues to be stunted after a decade or addition of reform, mainly where advancement in banking reforms is inadequate. The banking…

Juvenile recidivism is a prevalent problem in the criminal justice system. Tackling reoffending remains a complex task requiring several strategies and aims. It involves research, acknowledgement of causes, factors, exploration, and evaluation of subgroups to generate long-term, positive changes in the lives of juvenile offenders. From gang violence to Interactive, Constructive, Active, and Passive (ICAP), researchers discover some of the reasons why juveniles reoffend and the kinds of intervention methods that may help or worsen the problem of juvenile recidivism. Intervention philosophies like surveillance, discipline, close monitoring may increase recidivism rates. estorative programs, counseling, skill building programs, as well as multiple coordinated services decrease recidivism rates.

Black Women: Diversity and Inclusion Programs - Are they really assisting?
In the last few decades, researchers, policymakers, economic development experts, and analysts of public policy are increasingly concentrating on the aspect of entrepreneurship in the African-American community, with respect to devising distinct strategies for facilitating economic success. Establishment of set-aside initiatives for minorities (or disadvantaged business initiatives) is one political strategy which serves as an instrument for enhancing small, poor businesses' chances of survival. Several of these businesses were African-American-owned and -run businesses (House-Soremekun, 2007; Chatterji, Chay & Fairlie, 2013). This paper will look into the economics-politics interrelationship, by analyzing the aforementioned disadvantaged business initiatives' effect on African-American businesswomen's economic outcomes.
Set-aside initiatives for minorities first developed during the 1930s, with President oosevelt's Great-Depression-era New Deal initiatives for addressing economic issues (House-Soremekun, 2007). The 1933 Unemployment elief Act prohibited discrimination against people on the basis of color,…

It assumes a person is in control of their own fate and not a victim to it. Starting at an early age, a unique style of life is created by the person and that life-style stays relatively constant throughout the remainder of life. Working toward success, connectedness with others, and contributions to society are considered hallmarks of mental health, as well as being motivated by goals, dealing with the tasks faced in life, and social interest. Birth order is considered important in understanding a person's current personality, yet the therapy is future-minded, rather than retrospective. (Psyweb Pro, 2006)

Slow model (1992) is an economic tool used to analyze a country economic growth. The principal conclusion of Slow model is that the accumulation of capital could not only account for the growth rate per person. To address the central question of economic growth, it is critical to move beyond the Slow model. Mankiw et al. (1992) incorporate economic tools such as FDI growth rate, trade, inequality, institutional quality and other core variables such as labor and capital to analyze the growth rate across countries,.
Objective of this paper is to use the core economic variables and non-core economic variables to investigate their potential impacts on the United States growth rates.

Pizza Shop Demand Forecasting
Pizza Company Entry: Consumer Demand Forecast
There are a number of issues a company needs to think about before entering any particular market. In an industry such as the food service industry, there are even more factors to consider. Entering into any market can be a gamble, yet food service is often even more vulnerable in regards to the already strong presence of successful competitors and the income levels of the consumer markets being served. Within this particular analysis, the data presented in the course shell will be used as a way to determine if the Pizza Company should enter this particular market, and if so, which conditions will be most desirable in order to facilitate the most successful entry into the market.
One of the best forecasting tools companies can use is regression forecasting in order to determine the potential for consumer demand…

Predictors of the Transition From Experimental to Daily Smoking Among Adolescents in the United States
By reviewing the methodology and analysis sections of the study, I discovered that the quantitative method used was a complex sampling design with restricted-use data. The authors of the study used data from the National Longitudinal Study of Adolescent Health as their focus, so they had the opportunity to study a large amount of data without being required to collect it from survey participants or interviews (Park, Weaver, & omer, 2009). Examined were strata at the individual student level and schools as clusters, as well as the subjects and their unique selection criteria (Park, Weaver, & omer, 2009). There were 134 schools and 90,000 students participating. Each of those students filled out a 45-minute questionnaire regarding expectations for the future, their friendships, and their health (Park, Weaver, & omer, 2009).
I found that the covariates,…

" To meet the criteria of a "champion," the top, middle and lower management has got to be not only at an advanced level, but also should be extremely valued. The top management should proactively encourage and advance the organizational goals, offering knowledge and assistance. Furthermore, it is vital that these "champions" make sure that employee complaint resolution endeavors are successfully executed. In one study, companies with devoted and advanced "champions" had been twice as probable to account that their organizations had been doing better than they anticipated (Yu, 2001). This shows that with top management support as well as advanced and knowledgeable employees can assist in increasing the organizational performance. In light of the aforementioned facts, we have chosen our third variable as top management support and our third hypothesis is:
Hypothesis three: The stronger the top management support, the higher the employee retention rates.

Discussion of the empirical results from the regression analysis
The results of the regression analysis support the predictions that each of the identified independent variables is an important and significant predictor of average life expectancy at the county level. Higher percentages of obese individuals, smokers, low rates of exercise and small numbers of active primary care physicians predicted lower average life expectances at the county level. These results echo past research that has linked these variables to specific health outcomes and highlight the importance of focusing on these issues as important areas for intervention with respect to improving health, reducing health care costs, and general health promotion.

The objective of this report is to investigate dependence structure between the home line of business and domestic motor line of business to determine the global amount of capital to hold for both lines of business. The paper uses the regression analysis and descriptive statistics to analyze the raw data collected for the losses on both lines of business. The results from the analysis reveal that there is little or no positive dependence structure between the two lines of business because the . Square value from the regression analysis output is 0.29, which is closer to 0. Moreover, there are higher losses in the domestic motor line of business than the home line of business. There is also higher volatility in the domestic motor line of business than home line of business. Thus, the report recommends that home line of business should attract more global capital than…

Demand for Money
The international community is currently facing the most severe crisis since the Great Depression of 1929 -- 1933. It started within the American real estate sector and soon expanded to the rest of the sectors, as well as to the rest of the global economies.
The causes and impacts of the crisis have often been discussed in the media and within the specialized literature, and the discussion is far from over. Still, this approach to the crisis is more descriptive and reflective. At this stage nonetheless, it is necessary to implement a proactive approach through which to promote solutions to overcoming the crisis.
Governments across the globe have each developed and implemented their own solutions to the crisis, ranging primarily from injecting capitals in the troubled industry sectors and companies, to efforts aimed at reducing federal costs. In the completion of these efforts, a crucial role is…

Thompson's research is highly relevant to school administrators and counselors throughout the country. Most schools in the United States will have a substantial number of African-American students. Their needs and those of their parents are not being addressed well enough. Establishing solid ties between schools and their communities will help improve pubic relations and may also help raise the academic performance standards for African-American children. School administrators, teachers, and counselors should be able to satisfy the needs of all parents and children.
The researcher used a questionnaire to gather data about perceptions of public schools. All participants were self-described as African-Americans. A high number of participants were dissatisfied with their children's high school teachers: a greater number than those dissatisfied only with their children's elementary school teachers. Thompson (2003) also found that the participants' perceptions of elementary school teachers was positively correlated with perceptions of high school teachers. Dissatisfaction with elementary school teachers and the educational environment usually meant that the same parents remained dissatisfied with the high school teachers and high school environment. The researcher suggests that the research gathered in the current study be used to improve community relations and more importantly, to improve the one-on-one relationships between all public school professionals and all parents. The author also notes that elementary school education provides a strong foundation for student math and literacy competency. Those competencies will carry over into middle and high school. Therefore, African-American students who did not receive an adequate early childhood education are less likely to thrive in later grades.
African-American parents varied with regard to the factors that influence their perceptions about public schools and their staff. Course materials and caliber of homework was one factor that impacted African-American parent perspectives. Some parents, however, attributed their children's success or failure to personal effort. Ohters noted that racism and race awareness might affect school performance. Regardless of perceived reasons for African-American student performance in school, the system must respond to the persistent achievement gap between black and white students. Thompson's (2003) research emphasizes the need to establish relationships with African-American parents early: before high school. Although the author does not offer any specific suggestions for policy change, some can be inferred. For example, African-American parents expressed a preference for educational materials that they deemed relevant and meaningful for their children (p. 10). Consulting with African-American parents when their children are still in elementary school might help those parents trust that the system is responsive to their needs and the needs of their children.
¶ … complexities of doing business in our virtual age, looking in particular at e-commerce but also asking how the presence of e-commerce on the market has affected traditional businesses as well. Once upon a time - that golden age - things were simple. You decided you wanted to grow up to be a bookstore owner. Or a hardware store manager. Or a florist. So you leased a store, bought some books, and lovingly hand-sold them to each customer who flocked to your door and then went home at night to count your money.
Of course, owning a bookstore or a hardware store or a flower shop was actually never that simple. But the picture now is even more complicated as virtual stores have entered the picture. Part of what makes engaging in e-commerce so difficult is that there are no paths that others have trod before one. And the…
