44. In generalization of Problem 8 of Chapter 7. let (Xvi' . ..• Xvp)' v = 1, . . . • n. be independent normal p-vectors with common covariance matrix and with means s " - '\' a a(i) lib,,; - i...J vjP} , j -I where A = (a.) is a constant matrix ofrank s and where the fJ's are unknown parameters. If OJ = Lej~(i). give explicit expressions for the elements of V and S for testing the hypothesis H : OJ = 0;0 (i = 1,. . . •p).
