摘要
本文在一特殊的共同均值模型和平方损失函数下，得到了共同均值参数β线性无偏估计∑ｍｉ＝１Ａｉｙｉ∑ｍｉ＝１Ａｉ＝Ｉｎ分别在线性估计类和齐次线性估计类中为可容许估计的充要条件。
Under a special common model and the square loss function,we have got the necessary and sufficient conditions for the unbiased linear estimates m i=1 A iy i of the common parameters β to be admissible in the class of linear estimates and in the class of homogeneous linear estimatesrespectively.
