Abstract.The asymptotic non-null distributions of
the likelihood ratio,
Lawley-Hotelling, and Bartlett-Nanda-Pillai test statistics for
the MANOVA procedure are obtained
when both the sample size and the dimension tend to infinity.
These tests are of equal power in the limit.
Using the asymptotic distributions of the three test statistics,
we compare their asymptotic power.
We derive a simple method for selecting the test of greatest power.
