Distribution and percentage points of LRC for testing multisample compound symmetry in the bivariate and the trivariate cases

摘要

The exact null distribution of the likelihood ratio test statistic for testing multisample compound symmetry of q Gaussian models (bivariate or trivariate) is obtained and percentage points for q ≤ 5 are computed. The inverse Mellin transform and calculus of residues are used to derive these results.
