| 摘 要： | 股票市场的收益率从分布的角度看,并不服从标准的正态分布,而是呈现出一种"尖峰、厚尾"的特征。本文对上海股票市场进行分析,采用几种方法对股指对数收益率进行正态分布检验,发现收益率更加接近于一种混合正态分布,本文利用混合辨析的思想得到了收益率分布的具体形式。

| Abstract: | From the distribution point of view, the yield of stock market doesn＇ t follow the normal distribution, but appears the property as ＂the peak, thick end＂. Shanghai Stock Exchange is analyzed in this paper, and the normal distribution test of the index＇ s logarithmic yield is made by several methods. It can be concluded that the yield approaches to the mixed normal distribution, and the specific form of the yield distribution is obtained by using the theory of mixed analysis. |
