摘要
本文讨论母体原点矩的线性有偏估计问题。给出了在均方误差意义x1K,X2k,······,Xnk的线性函数优于样本原点矩xk的充分必要条件以及母体原点矩的具有x1k,x2k,···,Xnk的线性函数形式的最优估计。
The problem for linear biased estimation of the population origin moment is discussed in this paper. The necessary and sufficient condition with respect to linear biased estimation superior to sample origin moment is given in the sense of mean square error,and the optimal linear estimators of the populition origin moment are obtained.
