Nonparametric estimate of spectral density functions of sample covariance matrices: A first step
arXiv:1211.3230 · doi:10.1214/10-AOS833
Abstract
The density function of the limiting spectral distribution of general sample covariance matrices is usually unknown. We propose to use kernel estimators which are proved to be consistent. A simulation study is also conducted to show the performance of the estimators.
