...Moreover, since the distribution of Q is invariant if multiplied on the left by a fixed orthogonal matrix, Q must possess the Haar invariant distribution discussed in Anderson (1958). Since the conditional distribution of Y'2Y2 is (except for a constant) a noncentral chi-squared distribution with noncentrality parameter I Z 12, and hence free of Q, we may express the quantity in (2....
