Introduction to Regression Analysis (Easy Statistics)

Book Synopsis: Regression Analysis is a major coursework for many research and statistics students. Although many know only about simple linear regression analysis, it actually expanded into non-linear regression analysis and multiple linear regression analysis as well. Non-linear regression analysis is used for data sets which do not have a linear relationship and multiple linear regression analysis is used for data sets with more than one independent variable. Most importantly, residual tests in regression analysis are used to confirm the stability and reliability of the regression model. Residual tests are a crucial point in any regression analysis, that a student must have knowledge on. Many students and researchers fail to analyze data sets properly due to lack of knowledge in all types of regression analysis. If you do not get a desirable and fitting regression model, then it must be that another regression model should be used for the data set. Furthermore, the books which are written on complex topics on regression analysis are not easy to understand. Identifying this shortage, the writer has dedicated her time into writing a comprehensible book on regression analysis covering the topics related to Correlation, Simple Linear Regression, Residual Tests, Non-Linear Regression, Multiple Linear Regression. Even the complex calculations are presented step by step, in an uncomplicated manner. The examples are solved using manual calculations and statistical software such as Minitab and R (RStudio Version 4.0.0). Concepts such as parameter testing, residual testing, ANOVA table, exponential regression models, quadratic regression models, partial F test, multicollinearity, best subsets regression, and stepwise regression are also explained with relevant examples. "Introduction to Regression Analysis" is a basic but complete guide to regression analysis. Even a beginner can easily self-study. Necessary commands and outputs are explicitly presented in each example. Interpreting outputs is one of the major struggles a student goes through in his or her research work. This book guides how to interpret regression analysis outputs properly. If you want to champion your knowledge on regression analysis, use this book. Read more.
