在迴歸模型的應用上，迴歸不適用的模型中，有部份因素來自於其共線性，共線性主要產生的原因有二： （1）來自於相似變數之間所產生的共線性 （2）一種是來自於複多項式模型假設所產生的共線性。 本篇論文針對複多項式模型所產生的共線性提供標準步驟及sas程式來解決此問題。 In analyzing the regression model, the inadequate of model are sometimes due to the multi-collinearity among the independent variables. There are two major cases of this kind, one is the use of some similarity variables another one is fitting the multi-polynomial model. This thesis is concern of the case of using multi-polynomial model. We will provide some useful algorithms to establish a standard procedure in applying the ridge regression to analyze this kind of unacceptable result.
