However, if the significance level is moderately large, then the correlation is insignificant and these two variables are not linearly related. The t statistics will determine the relative significance of each variable in the model. As a guide on the useful predictors, note for t values well, -2 or above +2. R squared is defined as the variation's proportion in the dependent variable and explained by the regression model. R square values range from 0 to 1.
The correlations table presents Pearson correlation coefficients, the significance values, as well as the number of cases containing non-missing values. Clearly, Pearson correlation coefficients presume that data are normally distributed. Values of the correlation coefficient are in the array from -1 to 1. Subsequently, the sign we can see in the correlation coefficient designates the direction of the relationship (+ or -). The fixed value shown by correlation coefficient indicates the strength, if the absolute values are larger it means, it has stronger relationships.
Moreover, if the significance level is very small, practically less than 0.05, then, it means that the correlation is significant at the same time the two variables are linearly related. However, if the significance level is moderately large, then the correlation is insignificant and these two variables are ...Download file to see next pagesRead More

...? Investigating the determinants of property crime in the United s Introduction This report is an investigation of the determinants of property crimes in the United States. By property crimes, typically the references is to burglary, larceny, theft and motor vehicle theft. We seek to gain an understanding of what socio-economic characteristics of a particular state make it more susceptible to a larger number of property crimes. Data and methodology By using multiple regression analysis, the report is in pursuit of obtaining statistical evidence for or against commonly held beliefs regarding causality of various factors and crime. We use a State-wide data set that includes a record of property crimes rates (CRIMES) as well as a record...

Multiple Regression

...?Multiple Regression 0 General Purpose Multiple regression is simply an extension of linear regression, a statistical process which seeks to find the linear relationship between an independent variable and a dependent variable. In the case of multiple regression, the main purpose is to find the linear relationship between the dependent variable and a number of independent variables (Yan & Su, 2009). Multiple regression is one of the most widely used tools in statistical analysis because it is a very good reflection of real world situations. That is, a certain outcome is almost always affected by a number of predictors rather than just a single one (Dekking, 2005). Oftentimes, when a model is too simple that it only contains one independent...

Regression Analysis

...? This paper is about analyzing the relationship between the benefits offered to an employee and his/her total, intrinsic and extrinsic job satisfaction. A study like this can help the management in retaining employees and in avoiding legal or ethical issues which could have surfaced if the employee is not satisfied with his job. Introduction In order to check the relationship between benefits and the intrinsic, extrinsic and total job satisfaction, 3 bivariate regressions are run. Using the regression equations the linear relationship between the independent variable (benefit) and the 3 sets of dependent variables (total job satisfaction, intrinsic job satisfaction and extrinsic job satisfaction) is established. Bivariate regression...

Regression Analysis Research Paper

...?Regression Analysis: A mathematical tool that is used in case of linear operations for comparisons and evaluation of two or more variables. It relates to the statistic branch of mathematics. It is also defined as the usage of data for yielding of a relationship between number of parameters and variables that are dependent and independent (Rae, 2008). The final outcome can be in form of plot, an equation derived or the net value. The effect so determined is in form of casual relationship between two variables, where the upward shoot or downward shoot in the value directly affects the other variable. Regression analysis finds large number of principles and applications in economics. It is an effective tool of mathematical analysis...

Multiple Regression

...? Multiple Regression Below is the data that I have been collecting to There is a difference between simple regression and multiple regression. Simple regression analysis is used to establish the relationship between one variable and the other. One set of the variables is the dependent variable and the other set is the independent variable. The independent variable changes and in turn affects the dependent variable. Simple regression is used to establish whether or not indeed the independent variable determines the change that takes place in the dependent variable. It is also used to establish the way in which the two variables are related, such that on having one of the variables, it is possible to predict its corresponding value using...

...? Regression analysis assumptions Regression analysis assumptions A summary of the assumptions used in the paper and justifications for using the same is briefly discussed. Assumption 1: Non-linearity assumption This assumption is pegged on the assumption there is no linear relationship between the studied variables. As a matter of fact, the use of this assumption is meant to abridge or rather offer basis for development of a hypothesis that the proposed relationship will fail to hold. It disputes the existence of a relationship between the proposed variables (Good & Hardin, 2009). In essence, it allows for evaluation of the fixed and random effects models in non-linear modeling frameworks and simply assumes parameter and variable non...

Linear Regression and Regression Analysis

...Linear Regression and Regression Analysis Regression is a technique in statistics that enables estimation of the relation existing among variables. The technique seeks to estimate the strength of the relationship between one variable with another or a set of variables. However, when applying this technique, the statistician makes assumptions with regard to the variables and their relationship. Regression is based on the assumptions that there exists a linear relationship between the involved variables and that they have an additive relationship. There are many regression techniques one of them being linear regression. Linear regression refers to an approach that involves modeling the relationship that exists between a dependent variable Y...

James Madison's 51st Federalist Paper

If this theory was seriously followed, it would suggest that the citizens must opt for the president, the legislators, as well as the judges. However, the framers identified certain realistic problems in making all the offices elective. Especially, the judicial branch would face problems because the typical person does not have knowledge about what qualifications judges ought to have. Judges must have great capability, but also not have any political pressures. While federal judges are selected for life, their philosophy will not be inclined via the president who appoints them or the senators whose permission the president will take.

All the arguments were generated due to his past life as he was in an aristocratic fami...

To social psychologists, human behaviour is because of the interaction of immediate social situations and mental states. Social Psychology is an interdisciplinary domain that combines the concepts of Sociology and Psychology and bridges the gap between them. It is focused on both the intrapersonal phenomena such as persuasion and attitudes, and interpersonal phenomena such as group dynamics and relations with others. Social Psychology is an essential tool for the improvement of our lives not only as a means of interacting and understanding others but also as a means of understanding ourselves in order to make a more relevant impact on the world around us.

Literature and the Individual in Early Modern Masterpieces Paper

...Virtue is Power in “The Prince” 6 September Virtue is Power in “The Prince” “The Prince,” since it was published in 1532,has been the product of numerous political and philosophical analyses and debates. As a political treatise, it both enjoyed respect and received condemnation. The term “Machiavellian,” in particular, has since been marred with negativity because it asserted the argument that Machiavelli strongly believed that the ends will always justify the means. Several writers, such as Ledeen (2010) and Cave (2002), however, stressed that Machiavelli did not directly espouse such an ends-justify-all-means directive, without clarifying the ability of leaders to remain virtuous at all times. This essay explores how Machiavelli...

Body and Conclusion of the Paper about Biodisel

... in air pollution. b. Null Hypothesis In justifying the alternate hypothesis, this research paper contains a contradicting null hypothesis which claims that biodiesel cannot reduce air pollution. Undeniably, biodiesel produces approximately 70% less carbon dioxide compared to conventional fossil fuels. However, biodiesel generates approximately 2% more NO2 compared to fossil fuels (Lewis 89). NO2 is a harmful pollutant which poses serious health impact to humans. Unlike CO2 and its global warming effects which are future oriented, increase in NO2 cause immediate danger to persons in form of respiratory complications. In addition, NO2 is a precursor for depletion of ozone layer; hence responsible for the increase of carcinogenic radiations...
