Distribution of Eigenvalues in Multivariate Statistical Analysis

Ten invariant multivariate testing problems involving the real, complex, or quaternion structure of covariance matrices are considered. In each problem the the maximal invariant statistic and its distribution are described, as well as the maximum likelihood estimators and likelihood ratio test statistics. These results are obtained by means of a new, unified method based on invariance arguments. of ca Statis cs Andersson s was done ile Washington.
