This extension provides a user interface for the SELECTPR ED command. It takes a specified set of predictor variables as input and selects a smaller subset for use in predictive modeling procedure s. A univariable method that considers each predictor in isolation is used, as opposed to the multivariable method of selecting predictors that is used by the Naïve Bayes Classifier extension. The Select Pre dictors extension supports both categorical and scale dependent varia bles. Large sets of predictors can be handled.
