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! |

CPI index reflects a certain period of life of residents in the purchase of consumer goods prices and service projects and trends in the extent of price changes over the relative few, the use of very wide, which includes China's CPI index of the number of information? This paper will explore the issue. This paper collected from 1951 to 2006 the annual CPI data, use simple descriptive statistics analyzed its mean, variance, skewness, kurtosis and normality, and other characteristics; then this paper describes an effort to establish suitable for CPI annual changes of the ARMA model, the pattern of changes in the CPI structural analysis model, from the true value, residual value and fit the timing plans that fit the general effect, further consideration of the abnormal value analysis; then the model amendment that an appropriate model. |

CPI index is the relative number which reflects the changes degree and tendency of the price of consumer goods and the service that residents purchase a certain time.The use of CPI is extremely widespread.How many information does CPI index of our country contain? This article will carry on the discussion to this question. This article has collected CPI annual datas from 1951 to 2006, firstly used the simple descriptive statistics to analyze the characteristics of its mean values,the variance, the skewness,the kurtosis and the normality and so on.Then this article mainly devotes to establish a ARMA model which is suitable to describe the CPI annual changes rule, carry on the structural model analysis to the CPI change rule.From the true value, the fitted value and the residual sequential chart, we can see the fitting effect to be ordinary.Therefore further analysis is carried on to the related unusual value. Then amend the model and obtain an appropriate model. 很用心的翻了半个多小时，还请楼主支持（个人水平有限，错误在所难免） |
