摘要: 研究多元线性模型在不等式约束下齐次线性估计和非齐次线性估计的可容许性, 刻画了二者之间的关系, 得到了齐次线性估计(非齐次线性估计)在齐次线性估计类(非齐次线性估计类)中是可容许的充要条件.

Abstract: The admissibility of both homogeneous and inhomogeneous linear estimators was investigated in a multivariate linear model with respect to an inequality restriction. The relationship between admissibilities of the two types of estimators was characterized. The necessary and sufficient conditions for a linear estimator LY(LY+L1) to be admissible in a class of homogeneous (nonhomogeneous) linear estimators under quadratic loss were obtained.

Key words: multivariate linear model, inequality restriction, linear estimator, admissibility
