✦ Synopsis

A new method for the choice of variables with the greatest discriminatory power in the location model for mixed variable discriminant analpis is presented in the paper. The procedure based on ' the multivariate discriminatory measure enables a simultaneous reduction of the number of discrete and continuous variables. The introduced criterion can be used for both optimal or stepwise selection of variable subset. As an example the resdta of the stepwise variable selection for some medical data are presented in the paper.
