In multiple linear regression, it is possible that some of the independent variables are actually correlated with one another, so it is important to check these before developing the regression model. If two independent variables are too highly correlated (r2 > ~0.6), then only one of them sho...
Multiple Regression is a special kind of regression model that is used to estimate the relationship between two or more independent variables and one dependent variable. It is also called Multiple Linear Regression(MLR). It is a statistical technique that uses several variables to predict the outcom...
Multicollinearity is the occurrence of high intercorrelations among two or more independent variables in a multiple regression model. Multicollinearity can lead to skewed or misleading results when a researcher or analyst attempts to determine how well each independent variable can be used most effectivel...

This final chapter provides an introduction into multivariate regression modeling. We will cover the logic behind multiple regression modeling and explain the interpretation of a multivariate regression model. We will further cover the assumptions this type of model is based upon. Finally, and using ...

Depending on the nature and behavior of a data set, different types of regression analysis may be appropriate. For example, if the data has a roughly linear relationship then a linear regression would be best, whereas logistic regression would be ideal a...
Methods to determine the validity of regression models include comparison of model predictions and coefficients with theory, collection of new data to check model predictions. comparison of results with theoretical model calculations, and data splitting or cross-validation in which a portion of the data...
Multicollinearity occurs when two or morepredictor variablesin a regression model are highly correlated with each other. In other words, one predictor variable can be used to predict another with a considerable degree ofaccuracy. This creates redundant information, skewing regression analysis results. ...
