On n/p-Asymptotic Distribution Of Vector Of Weighted Traces Of Powers Of Wishart Matrices

Sammanfattning

The joint distribution of standardized traces of 1/n XX' and of (1/n XX')(2), where the matrix X : p x n follows a matrix normal distribution is proved asymptotically to be multivariate normal under condition n/p ->(n,p ->infinity) c> 0. Proof relies on calculations of asymptotic moments and cumulants obtained using a recursive formula derived in Pielaszkiewicz et al. (2015). The covariance matrix of the underlying vector is explicitely given as a function of n and p.
