Statistical eigen-inference from large Wishart matrices
大型Wishart矩阵的统计特征值推断
We consider settings where the observations are drawn from a zero-mean multivariate (real or complex) normal distribution with the population covariance matrix having eigenvalues of arbitrary multiplicity. We assume that the eigenvectors of the population covariance matrix are unknown and focus on inferential procedures that are based on the sample eigenvalues alone (i.e., “eigen-inference”). Results found in the literature establish the asymptotic normality of the…
