摘要
提出线性模型中回归系数的多k类广义压缩最小二乘估计的概念.在均方误差的意义下,给出了该估计一致优于最小二乘估计的充分条件.
In this paper, we proposed the multiple k-class generalized shrunkenleast squares estimator for coefficient of regression in linear regression model, and got asufficient condition under which the multiple k-class generalized shrunken least squanesestimator is uniformly better than the least squares estimator in sense of mean square er-ror.
