Abstract

Given a multivariate complex centered Gaussian vector Z = (Z1, . . . , Zp) with non-singular covariance matrix S, we derive sufficient conditions on the nullity of the complex moments and we give a closed-form expression for the non-null complex moments. We present conditions for the factorisation of the complex moments. Computational consequences of these results are discussed.
