Spiked Eigenvalues of High-Dimensional Separable Sample Covariance Matrices
Zhang, Bo - 2019
This paper establishes asymptotic properties for spiked empirical eigenvalues of sample co- variance matrices for high-dimensional data with both cross-sectional dependence and a dependent sample structure. A new finding from the established theoretical results is that spiked empirical...

Spectra of Large-Dimensional Sample Covariance Matrices
Serdobolskii, V.I. - 2018
Limit spectral theory of sample covariance matrices of increasing dimension was recently used as a base for the … investigation of fundamental relations of this theory (of the “canonical equations”) that thus prove the accuracy of asymptotic …
