On Non-Null Distributions Connected with Testing Reality of a Complex Normal Distribution
复正态分布协方差矩阵实值性检验的备择分布
Certain polynomials of a skew-symmetric matrix are considered. These polynomials can be expressed in terms of the zonal polynomials on the Hermitian matrices, and they are used to obtain a series expansion for the density of the non-null distribution of the maximal invariant corresponding to the problem of testing for reality of the covariance matrix of a complex multivariate normal distribution.
