| 摘 要： | 统计学研究的出发点是数据集D.本文把D纳入线性回归模型M.当D有复共线性现象时,以最小二乘估计为基础的影响分析往往失效,于是,本文探讨以有编估计为基础的影响分析.

| Abstract: | Statistical research starts from a data set. In this paper,the data set is brought into a lin-ear regression model. When there is multi-collinearity in the data set,the influence analysis,based on the least squares estimator,often loses its efficacy. Thus,this paper studies the in-fluence analysis based on biased estimation. |

| Keywords: | Influence analysis multi--collinearity influential point biased estimation |
