研究了线性模型中LIU估计的影响分析问题,得到了原模型与数据删除、方差扰动及均值漂移模型间——线性回归有偏估计(LIU)估计的关系式,给出了影响度量的计算公式。
The influence analysis on Liu estimator in the linear regression model will be studied and derived the relations of Liu estimate between original linear model and data deletion model,variance perturbation model,mean-shift model,the formulas are given which measure the influence.
