Abstract:

This article presents a statistic for testing the sphericity in a GMANOVA-MANOVA model with normal error. It is shown that the null distribution of this statistic is beta and its nonnull distribution is given in series form of beta distributions.

Key words: GMANOVA-MANOVA model, sphericity test, zonal polynomial
