Stepwise multiple regression is a technique that can be used to select a subset of the most important independent variables from a larger set of variables. It sequentially adds or removes independent variables to the model based on their contribution to the overall predictive power of the model. This helps to identify the most important variables and can improve the efficiency of the model without sacrificing predictive power.
