Stepwise regression allows variables to enter and leave the model based on their statistical significance, which can lead to a more parsimonious model with better predictive performance. While forward selection and backward elimination are also commonly used in multiple regression, they have limitations and may not always result in the best model. Residual analysis, on the other hand, is a diagnostic tool used to evaluate the adequacy of the selected model and is not a procedure for variable selection.
