Stepwise regression allows variables to enter and leave the model at different stages of its development based on their statistical significance. This is more flexible than forward selection or backward elimination which only allow variables to enter or leave at specific stages, and is a commonly used procedure in multiple regression analysis. Residual analysis and chi-square test are not relevant procedures for selecting variables in multiple regression analysis.
