Empirical Bayes Estimation with Side Information: A Nonparametric Integrative Tweedie Approach

no code implementations11 Aug 2023 Jiajun Luo, Trambak Banerjee, Gourab Mukherjee, Wenguang Sun

As the dimension of the auxiliary data increases, we accurately quantify the improvements in estimation risk and the associated deterioration in convergence rate.

Integrative conformal p-values for powerful out-of-distribution testing with labeled outliers

1 code implementation23 Aug 2022 Ziyi Liang, Matteo Sesia, Wenguang Sun

This paper develops novel conformal methods to test whether a new observation was sampled from the same distribution as a reference set.

Locally Adaptive Algorithms for Multiple Testing with Network Structure, with Application to Genome-Wide Association Studies

1 code implementation22 Mar 2022 Ziyi Liang, T. Tony Cai, Wenguang Sun, Yin Xia

Linkage analysis has provided valuable insights to the GWAS studies, particularly in revealing that SNPs in linkage disequilibrium (LD) can jointly influence disease phenotypes.

Large-Scale Shrinkage Estimation under Markovian Dependence

no code implementations4 Mar 2020 Bowen Gang, Gourab Mukherjee, Wenguang Sun

We consider the problem of simultaneous estimation of a sequence of dependent parameters that are generated from a hidden Markov model.

Structure-Adaptive Sequential Testing for Online False Discovery Rate Control

no code implementations28 Feb 2020 Bowen Gang, Wenguang Sun, Weinan Wang

Consider the online testing of a stream of hypotheses where a real--time decision must be made before the next data point arrives.

False Discovery Rate Control Under General Dependence By Symmetrized Data Aggregation

1 code implementation27 Feb 2020 Lilun Du, Xu Guo, Wenguang Sun, Changliang Zou

We develop a new class of distribution--free multiple testing rules for false discovery rate (FDR) control under general dependence.
