## Stepwise Regression

Stepwise Regression using MInitab shall be discussed through this article. Stepwise regression removes and adds variables to the regression model for the purpose of identifying a useful subset of the predictors. Minitab provides three commonly used procedures: standard stepwise regression...[ read more ]
