摘要
本文在文献[1]的基础上,提出了线性回归模型参数的泛BC估计.把有偏压缩估计类的压缩系数由一维推广到多维,即由常数推广到矩阵向量,从而推出其一些优良性质.
On the basis of [1] this paper brings forward a generalized BC estimation of the linear regressive model parameter,and generalizes contraction coefficient of biased contraction estimation from one dimension to multidimensionality.also some good properties are proved.
