英文摘要 | This article respectively provides sufficient conditions and necessary conditions of matrix linear estimators of an estimable parameter matrix linear function in multivariate linear models with and without the assumption that the underlying distribution is a normal one with completely unknown covariance matrix. In the latter model, a necessary and sufficient condition is given for matrix linear estimators to be admissible in the space of all matrix linear estimators under each of three different kinds of quadratic matrix loss functions, respectively. In the former model, a sufficient condition is first provided for matrix linear estimators to be admissible in the space of all matrix estimators having finite risks under each of the same loss functions, respectively. Furthermore in the former model, one of these sufficient conditions, correspondingly under one of the loss functions, is also proved to be necessary, if additional conditions are assumed.
