| 摘 要： | 本文在变量选择问题的基础上，提出了一种新的图示模型──减变残差图。并给出它的两种推广形式：均值平移异常值检验图和部分影响诊断图。通过它们不但可以容易地考察一个变量在模型中的作用和检验异常值，而且可以诊断样本点对模型和变量的影响大小。

| Abstract: | In this paper, a new graphical model called subtracting variable residual (SVR) plot is presented on the basis of variable selection problem, and its two extensions are given. They can be used not only to determine the importance of an explanatory variable and to find outliers in the regression model,but also to detect some cases with influence on the model and vaviables. |
