Multivariate tests of means in independent groups designs. Effects of covariance heterogeneity and nonnormality.

Abstract

Health evaluation research often employs multivariate designs in which data on several outcome variables are obtained for independent groups of subjects. This article examines statistical procedures for testing hypotheses of multivariate mean equality in two-group designs. The conventional test for multivariate means, Hotelling's T2, rests on certain… (More)
