Local Laws and Edge Universality for Noncentral Sample Covariance Matrices

Can Hu, Jiang Hu, Zhidong Bai

We consider the real noncentral sample covariance matrices $W = Y Y^{⊤}$ with $Y = A + Σ^{1/2} X$ . Here $A \in R^{M \times N}$ is deterministic, $Σ\in \mathbb{R}^{M\times…

Functional CLT for general sample covariance matrices

Jian Cui, Zhijun Liu, Jiang Hu +1

This paper studies the central limit theorems (CLTs) for linear spectral statistics (LSSs) of general sample covariance matrices, when the test functions belong to $C^{3}$ , the class…
