受约回归系数之线性估计的可容许性

Admissibility of Linear Estimators ors of its Regression Coefficient with Restricted Homogeneous Linear Equality Under the Quadratic Loss Function

讨论了在二次损失下，带齐线性约束的一般ＧＭ模型回归系数之线性估计的可容许性。

Abstract For a general GM model with restricted homogeneous linear equality,this paper deals with the admissibility of linear estimators of its regression coefficient Safficient and necessary conditions are given under which a linear estimator of conditionally estimable linear function of the regression coefficient is admissible Key wrods regression coefficient;conlitionally estimable;linear function;linear estimators,admissibility
