Some properties of the distribution of the logarithm of non-central F
非中心 F 分布对数的若干性质
E2= fiF* f2 +f1 F* it was studied by Wishart (1932) and by Tang (1938) who gave a few values of the probability integral. Patnaik (1949) approximated to the distribution of F* by a central F distribution. It is clear that any tabulation of the distribution of F* will be a formidable proceeding. There are three parameters fl, f2 and A which intervene explicitly. If we are concemed with the power function of the F-test there must also be the values of the central F at which…
