Bias-Corrected Multiplier Bootstrap Inference for Spectral Edges of Large Covariance Matrices
Xiucai Ding, Yichen Hu, Jiahui Xie
Inference for spectral edges of large covariance matrices is a fundamental problem in high-dimensional statistics. A major difficulty is that the largest non-spiked sample eigenval…

On the edge eigenvalues of sparse random geometric graphs
Xiucai Ding, Yichen Hu
In this paper, we study the edge eigenvalues of random geometric graphs (RGGs) generated by multivariate Gaussian samples in the sparse regime under a broad class of distance metri…
