摘要:
对居民消费价格指数及各影响因子进行分析，运用逐步回归法得到最优回归模型，得出居民消费价格指数最重要的几个影响因子；对回归模型的可行性进行了验证，结果显示所得模型精度达到99.8982%，具有可行性，并对结果进行分析，提出一些建议。We obtain the best regression model by using stepwise regression method and analyzing the con-sumer price index and its impact factors; then we get some most important impact factors of it. The feasibility of the regression model is proved in the paper. The results show that the accuracy of model reaches to 99.8982%, so it have feasibility. Some suggestions based on the results are given at last.
