GUPTA, Arjun K.; NAGAR, Daya K. and VELEZ-CARVAJAL, Astrid M.. Unitary invariant and residual independent matrix distributions. Comput. Appl. Math. [online]. 2009, vol.28, n.1, pp.63-86. ISSN 2238-3603. http://dx.doi.org/10.1590/S0101-82052009000100004.
Define Z13 = A1/2Y(A1/2)H (A and Y are independent) and Z15 = B1/2Y(B1/2)H (B and Y are independent), where Y, A and B follow inverted complex Wishart, complex beta type I and complex beta type II distributions, respectively. In this article several properties including expected values of scalar and matrix valued functions of Z13 and Z15 are derived.
