摘要
In this paper, we derive a recurrence formula for evaluating mathematical expectations of X'A(1)XX'A(2)X ... X'A(n)X, where X similar to N-p(0,Phi) and A(j), j = 1, 2, ..., n are (p x p) nonstochastic symmetric matrices. Subsequently, this recurrence formula is applied to some specific problems. Various related results will also be reported.
