| 摘 要： | 对CPI值进行预测，对我国相应部门做出正确的宏观决策有积极意义．本文采用应用非常广泛的一类随机模型——统计回归模型，首先找到关于CPI指数变化的影响因素，搜集相关的大量数据；然后通过应用主成分分析法找出影响CPI的3个主要因素；最后基于3因素的数据，通过统计分析，建立回归模型，对短期内的情况进行预测．

| Abstract: | To predict the value of the CPI has a positive meaning for that China's relevant departments to make correct macro-strategies.A class of stochastic model,which was used very widely-the statistical regression model was used.First of all,the factors to influence CPI were found,and the related large amount of data was collected.Then through principal component analysis,three most important factors were found out.At last,based on the data of three factors,through statistical analysis,regression model was set up... |
