The main approaches for stepwise regression are: • Forward selection, which involves starting with no variables in the model, testing the addition of each variable using a chosen model fit criterion, adding the variable (if any) whose inclusion gives the most statistically significant improvement of the fit, and repeating this process until none improves the model to a statistically significant extent. bound latWebregression. An exit significance level of 0.15, specified in the slstay=0.15 option, means a variable must have a p-value > 0.15 in order to leave the model during backward selection and stepwise regression.
