【Abstract】 In parameter estimation the parameters to be estimated are often matrices.To compute the maximum likelihood estimations of parameters, derivates of matrices are needed. In some cases, the derivation computation of matrices is difficult. In this paper, Fisher formula is applied to the calculation of obtaining some formulas in the factor analysis model and the repeated measuring model, which are relevant to derivation computation of matrices.更多还原
