Extract

Let θ be an n-dimensional random vector with components θ1, θ2, …, θn and let itscumulants

be defined as usual by the identity

where x1, x2, …, xn are purely imaginary variables, E denotes expectation, and

Let θ(1), θ(2), …, θ(R) be independent and identically distributed (i.i.d.) random vectors each with the same distribution as θ, where R = r1 + r2 + … + rn = |r|, the order of the cumulant Kr. Let θ* have the components
