在评价一个正态线性棋型的准确性时，偏残差图、增加变量图和构造变量图是三个有用的过程。
The added variable plot, partial residual plot and constructed variable plot are three useful diagnostic procedures in assessing the accuracy of a normal linear model.
通过减变量残差图，不但可以容易地考察一个变量在模型中的作用，而且可以诊断样本点对模型和变量的影响大小。
It can not only be used to determine the importance of an explanatory variable in the regression model, but also to detect some cases with influence on the model and variables.
