海南省CPI数据一致性的统计分析

Statistical Analysis of Data Consistency for CPI Data of Hainan Province

选择1988—2008年海南省CPI的统计数据,从Weibull分布中参数的极大似然估计的角度,在形状参数未知的情况下,用随机模拟的方法给出其分位数,很好地解决了异常值的问题,并对异常值所对应的经济学含义给出了合理的解释.

In our report, the CPI data of Hainan Province from 1988 to 2008 were collected, and based on the Maximum Likehood Estimate of parameters in Weibull distribution, the method of random simulation in the ease of the MLE of unknown shape parameter was used to derive the quantile fraetile, which solves the issue of outliers and gives a reasonable explain on outlier in the point of economic implications.
