| 摘 要： | 针对线性回归模型的多重复共线性问题，在理论上，引入方差膨胀因子，从量化的角度探测线性回归模型的多重复共线性；并采用岭迹分析法对此类模型的结构辨识方法展开研究，归纳了岭迹选择主元的若干原则，并通过实际计算证实了该方法的有效性。

| Abstract: | Directed at the collinearity problem of linear regression model, in theory variance inflation fator is introduced to detect the linear regression model collinearity from the point of view of quantification and use ridge trace analysis method to research the indentification method of the model's structure. On the basis of real calculation, principles of Ridge Trace Selection Procedure are concluded. |
