【Abstract】 Two problems on simultaneous hypothetical testing of location and scale parameters in a growth curve model are considered in this paper.Let Y～N_p,N（BζA, Σ, I,）.where B and A are known matrices of orders p×q and m×N respectively, ζ an unknown location parameter matrix of order q×m, and Σ an unknown positive definite scale parameter matrix of order p×p.In section 2, likelihood ratio test procedures are given for the following null hypotheses: 1) H₁: ζ=0,Σ=I 2) H₂: ζ=0,Σ=σ² G.where G is a known positive definite matrix, and σ a unknown positive number. The hth moments and the distributions of these statistics under H_i are given in section 3.更多还原
