Estimating the local false discovery rate under an unknown symmetric null
Daniel Xiang, William Fithian, Nikolaos Ignatiadis +2
This paper is concerned with estimating the local false discovery rate (lfdr) in a two-groups model where the only assumption regarding the null distribution is symmetry about zero…
Posterior consistency of Pólya trees for deconvolution under the linear model
Nakul Shenoy, Asaf Weinstein
Several recent works have addressed the problem of deconvolution under a linear model, where the goal is to estimate a completely unknown from a vector of noisy observations…
On the Minimum Attainable Risk in Permutation Invariant Problems
Asaf Weinstein
We introduce a broad class of permutation invariant problems by extending the standard decision theoretic definition to allow also selective inference tasks, where the target is sp…
Empirical Bayes Variable Selection with Lasso Statistics in the AMP Framework
Lina Hidmi, Asaf Weinstein
The Lasso is one of the most ubiquitous methods for variable selection in high-dimensional linear regression and has been studied extensively under different regimes. In a particul…
Nonparametric Shrinkage Estimation in High Dimensional Generalized Linear Models via Polya Trees
Asaf Weinstein, Jonas Wallin, Daniel Yekutieli +1
Regularization in fitting regression models has been a highly active topic of research in the past few decades, but most of the existing methods are designed for particular situati…
