| Abstract: | Based on the CPI data of Sichuan province from 2000 to 2010 and some influencing factors,the multiple linear regression model of CPI data is built by SPSS17.0.The multicollinearity in model is modified based on ridge regression,and a adjusted model is obtained.The result shows that this method has certain practicability. |
