Quantitative CLT for linear eigenvalue statistics of Wigner matrices

Zhigang Bao, Yukun He

In this article, we establish a near-optimal convergence rate for the CLT of linear eigenvalue statistics of Wigner matrices, in Kolmogorov-Smirnov distance. For all test functions…

Statistical inference for principal components of spiked covariance matrices

Zhigang Bao, Xiucai Ding, Jingming Wang +1

In this paper, we study the asymptotic behavior of the extreme eigenvalues and eigenvectors of the high dimensional spiked sample covariance matrices, in the supercritical case whe…

On Cramér-von Mises statistic for the spectral distribution of random matrices

Zhigang Bao, Yukun He

Let and be the empirical and limiting spectral distributions of an Wigner matrix. The Cramér-von Mises (CvM) statistic is a classical goodness-of-fit statisti…

Principal components of spiked covariance matrices in the supercritical regime

Zhigang Bao, Xiucai Ding, Jingming Wang +1

In this paper, we study the asymptotic behavior of the extreme eigenvalues and eigenvectors of the spiked covariance matrices, in the supercritical regime. Specifically, we derive…

Singular vector and singular subspace distribution for the matrix denoising model

Zhigang Bao, Xiucai Ding, Ke Wang

In this paper, we study the matrix denosing model , where is a low-rank deterministic signal matrix and is a random noise matrix, and both are . In the sc…
