摘要
本文建立了协方差扰动模型Stein估计与G-M模型Stein估计、数据删除模型Stein估计的关系,推出了Stein估计基于有偏估计的广义Cook距离。
In this paper,we set up the relationships among the Model with covariance matrix disturbance for Stein estimate and the G-M model for Stein estimate,data deletion Model for stein estimate,with the result that inferring the general Cook distance （based on the Stein estimate） of the biased estimate.
