Abstract

In this paper, we give a general  recursive  formula  forE[∏ki=0Tr{Wmi}], whereW∼ Wp(I,n) denotes a real Wishart matrix. Formulas for fixed n,pare presented as well as asymptotic versions when npn,p→∞→c,  i.e.,  when the so called Kolmogorov condition holds. Finally, we show application of the asymptotic moment relation when deriving moments for the Marchenko-Pastur distribution (free Poisson law). A numerical illustration using implementation of the main result is also performed
