摘要翻译:
在本研究中,我们试图根据随机矩阵理论(RMT)来确定股票市场数据中的特征值是如何随着组成相关矩阵的股票数量的变化而变化的。具体来说,我们测试了特征值性质的变化作为相关矩阵中股票数量和类型的函数。我们确定特征值的值与股票的数量成比例增加。此外,我们注意到,最大的特征值保持其相同的性质,无论数量和类型,而其他特征值表现出不同的特征。

英文摘要:
In this study, we attempted to determine how eigenvalues change, according to random matrix theory (RMT), in stock market data as the number of stocks comprising the correlation matrix changes. Specifically, we tested for changes in the eigenvalue properties as a function of the number and type of stocks in the correlation matrix. We determined that the value of the eigenvalue increases in proportion with the number of stocks. Furthermore, we noted that the largest eigenvalue maintains its identical properties, regardless of the number and type, whereas other eigenvalues evidence different features.
