线性估计可容许性的一个新证明

对一般的线性模型 :Y～ (Xβ ,σ2V)和Y ～ (Xβ ,V)其中X和V为已知矩阵 ,σ>0和 β∈RP为参数 .

For the general linear model Y～(Xβ,σ 2V) and Y～(Xβ,V), where X and Y are known matrices, σ>0 and β∈R P are parameters. This paper has given a simpler proof which gives the necessary and sufficient conditions for a lineaar estimator LY+d of the estmable function SXβ to be admissible in the class of all linear estimators.
