Wilk's Λ criterion is used to test the equality of the mean vectors of k p-variate normal distributions. The distribution of the test statistic can be expressed as a function of several independent beta distributions. The power function of this test is compared with the Lawley–Hotelling trace and Philbi's trace test for MANOVA.
