| 摘 要： | 针对多元正态线性模型,根据Zellner提出的平衡损失函数,对其进行变形,定义了更一般的平衡损失函数。研究了在该损失下,多元正态线性模型回归系数矩阵的线性估计在一切估计类中的可容许性,并给出了充要条件。该方法同样适用于线性估计类中的可容许性以及其他的可容许性的研究。

| Abstract: | For a given multivariate normal linear model,a new generalized balanced loss function is defined by modifying the balanced loss function given by Zellner.The admissibility of linear estimators of the regression coefficients matrix of the multivariate normal linear model in the class of all estimators under this loss has been studied,the necessary and sufficient condition is given.This method can also be used in the study of the admissibility of linear estimators in the class of all linear estimators and other definitions of admissibility. |
