Empirical Bayes mean estimation with nonparametric errors via order statistic regression on replicated data
Nikolaos Ignatiadis, Sujayam Saha, Dennis L. Sun +1
We study empirical Bayes estimation of the effect sizes of units from noisy observations on each unit. We show that it is possible to achieve near-Bayes optimal mean square…

Two-component Mixture Model in the Presence of Covariates
Nabarun Deb, Sujayam Saha, Adityanand Guntuboyina +1
In this paper, we study a generalization of the two-groups model in the presence of covariates --- a problem that has recently received much attention in the statistical literature…

On the nonparametric maximum likelihood estimator for Gaussian location mixture densities with application to Gaussian denoising
Sujayam Saha, Adityanand Guntuboyina
We study the Nonparametric Maximum Likelihood Estimator (NPMLE) for estimating Gaussian location mixture densities in -dimensions from independent observations. Unlike usual lik…
