R²= 4.33% of the variation in the dependent variable RET is explained by the variation of the independent variables: GRI, SAT, TEN, Age, and MBA. We cannot assume from the low R squared that the model is useless because there might be one or more independent variables that are not significant to the dependent variable. Also, we cannot question the fact that the OLS are not accurate just by looking at the low R squared. In the opposite, adding new independent variables do increase the R squared even

between one dependent and one independent variable. After performing an analysis, the regression statistics can be used to predict the dependent variable when the independent variable is known. Regression goes beyond correlation by adding prediction capabilities. Types Of Regression Analysis: Most widely used two types of regression analysis are- I [pic] Linear Regression Analysis: When the regression is conducted by two variables or factors
