FarmTest: Factor-Adjusted Robust Multiple Testing with Approximate False Discovery Control
Jianqing Fan, Yuan Ke, Qiang Sun +1
Large-scale multiple testing with correlated and heavy-tailed data arises in a wide range of research areas from genomics, medical imaging to finance. Conventional methods for esti…
Graphical Nonconvex Optimization for Optimal Estimation in Gaussian Graphical Models
Qiang Sun, Kean Ming Tan, Han Liu +1
We consider the problem of learning high-dimensional Gaussian graphical models. The graphical lasso is one of the most popular methods for estimating Gaussian graphical models. How…
Adaptive Huber Regression
Qiang Sun, Wenxin Zhou, Jianqing Fan
Big data can easily be contaminated by outliers or contain variables with heavy-tailed distributions, which makes many conventional methods inadequate. To address this challenge, w…
Counting Process Based Dimension Reduction Methods for Censored Outcomes
Qiang Sun, Ruoqing Zhu, Tao Wang +1
We propose a class of dimension reduction methods for right censored survival data using a counting process representation of the failure process. Semiparametric estimating equatio…
