Staircase phase transitions for the largest eigenvalue of heavy-tailed sample correlation matrices
Yanpeng Li, Zeqin Lin, Yiming Liu +2
We establish staircase phase transitions for the largest eigenvalue of heavy-tailed sample correlation matrices formed from a data matrix with i.i.d. real entries of…

Asymptotic limits of spiked eigenvalues and eigenvectors of signal-plus-noise matrices with weak signals and heteroskedastic noise
Xiaoyu Liu, Yiming Liu, Guangming Pan +2
This paper is to study a signal-plus-noise model in high dimensional settings when the dimension and the sample size are comparable. Specifically, we assume that the noise has a ge…
