High dimensional matrix estimation through elliptical factor models

Xinyue Xu, Huifang Ma, Hongfei Wang +1

Elliptical factor models play a central role in modern high-dimensional data analysis, particularly due to their ability to capture heavy-tailed and heterogeneous dependence struct…

Adaptive Rank-based Tests for High Dimensional Mean Problems

Yu Zhang, Long Feng

The Wilcoxon signed-rank test and the Wilcoxon-Mann-Whitney test are commonly employed in one sample and two sample mean tests for one-dimensional hypothesis problems. For high-dim…

Power Comparison between High Dimensional t-Test, Sign, and Signed Rank Tests

Long Feng

In this paper, we propose a power comparison between high dimensional t-test, sign and signed rank test for the one sample mean test. We show that the high dimensional signed rank…

Sorted Concave Penalized Regression

Long Feng, Cun-Hui Zhang

The Lasso is biased. Concave penalized least squares estimation (PLSE) takes advantage of signal strength to reduce this bias, leading to sharper error bounds in prediction, coeffi…
