针对股票间相关性,通过相关分析、系统聚类分析、网络构建等多种方法,以收益率为对象,建立股票间相关性度量指标模型,运用软件 Excel、Matlab 得出股票相关系数矩阵,并设置合适的阈值,利用软件Netdraw 构建出基于最佳阈值和相关系数所对应的股票网络。然后从所建网络出发,对中国股票市场中的板块进行聚类分析,最终建立起一个以收益率为指标来研究股票相关性的模型,为研究股票相关性提供了一个相对比较完善的方案。
Correlation Analysis,hierarchical cluster analysis,network construction and some other methods, targeting yield rate,are used to build the Metrics Model of the correlation of stocks.Correlation Coefficient Matrix is finalized via Excel and Matlab.And by setting proper threshold value,utilizing Netdraw,Stock Network is set up based on optimal threshold value and correlation coefficient.By Clustering Analysis on the module in China’s stock market,the mathematic model about the study of Stocks Correlation is ultimately constructed on yield rate,which is considered as a relatively complete solution for stock correlation studies.
