In this paper, we introduce the method of matrix differentials, by which we can derive some exact distributions In 1947, Prof. P. L. Hsu gave lectures in mul-tivariate analysis at the University of North Carolina, in which he developed the matrix differential technigue for finding Jacobians of some matrix transformations. In 1951, W, L. Deemer and I; Olkin prepared an expository paper giving a systematic development with all proofs. By this method, we got some exact distributions, which appeared in [2] and other papers. |
