Abstract

Under weighted balanced loss function, we obtain the best linear unbiased estimator of regression coefficient in general Gauss–Markov model and discuss the admissibility of linear estimators of the regression coefficient with respect to an ellipsoidal constraint. We establish necessary and sufficient conditions for the admissibility of the linear estimators Ay(Ay+a) among the class of homogeneous and inhomogeneous linear estimators, respectively.

加权平衡损失下关于椭球约束的一般高斯-马尔可夫模型的可接纳性

摘要

在加权平衡损失函数下,我们获得了一般高斯-马尔科夫模型中回归系数的最佳线性无偏估计量,并讨论了回归系数线性估计量相对于椭球约束的可接受性。我们为线性估计量的可接受性建立了充分必要条件一个是的(一个是的+一个) 分别属于齐次和非齐次线性估计量。
