可能含有多个散装组分的加标样本协方差阵

Spiked sample covariance matrices with possibly multiple bulk components

Xiucai Ding

摘要:

本文研究了具有多个体成分的加标样本协方差阵的特征值和特征向量的收敛极限和收敛速度。我们的模型是Johnstone的尖峰协方差阵模型的扩展。基于我们的结果,我们可以扩展许多统计应用的基础上Johnstone的尖峰协方差阵模型。

英文摘要:

In this paper, we study the convergent limits and rates of the eigenvalues and eigenvectors for spiked sample covariance matrices whose spectrum can have multiple bulk components. Our model is an extension of Johnstone's spiked covariance matrix model. Based on our results, we can extend many statistical applications based on Johnstone's spiked covariance matrix model.
