Simultaneous Procedures in Discriminant Analysis Involving Two Groups

Abstract

A simrdtaneous test, procedure is proposed for redrIcing the number of variables required to discriminate between two multivariate normal poprdatiorls. This procedure forms part of a wider simrdtaneolls procedure, for detailed descriptive analysis of group differences, which isolates subsets of variables providing significant discrimination as well as sltbsets of variables providing essentially as milch grollp separation as the original set of variables.
