CPI指数是反映一定时期居民所购买的生活消费品价格和服务项目价格变动程度和趋势的相对数,使用极为广泛,那我国的CPI指数包含了多少信息呢?本文将对这个问题进行探讨。
本文收集了1951至2006年的CPI的年度数据,先用简单的描述性统计的方法分析了其均值、方差、偏度、峰度和正态性等特点;然后本文主要致力于建立适合描述CPI年度变化规律的ARMA模型,对CPI的变化规律进行结构性的模型分析,从真实值、拟合值和残差的时序图看出拟合效果一般,所以进一步考虑对有关的异常值进行分析;然后对模型进行修正,得出一个合适的模型。


是我的论文,中文摘要部分.我的英语不行. 请英语好的高手给翻译翻译吧.谢谢!
