Let W be a multivariate t -vector with dimension d and degrees of freedom m, with m > 4, then E W = 0, and . From Theorem 1, the kurtosis parameter in Eq. 5.3 becomes , and the kurtosis κ4 = 3 d2κ0. Moreover, if , where Σ = A⊤A, then E X = μ , and kurtosis parameter κ0 and kurtosis κ4 are the same as for W.
