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.

Bootstrapped Edge Count Tests for Nonparametric Two-Sample Inference Under Heterogeneity

no code implementations26 Apr 2023 Trambak Banerjee, Bhaswar B. Bhattacharya, Gourab Mukherjee

In this regime, we study the asymptotic behavior of weighted edge count test statistic and show that it can be effectively re-calibrated to detect arbitrary deviations from the composite null.

Structured Dynamic Pricing: Optimal Regret in a Global Shrinkage Model

no code implementations28 Mar 2023 Rashmi Ranjan Bhuyan, Adel Javanmard, Sungchul Kim, Gourab Mukherjee, Ryan A. Rossi, Tong Yu, Handong Zhao

We consider dynamic pricing strategies in a streamed longitudinal data set-up where the objective is to maximize, over time, the cumulative profit across a large number of customer segments.

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.
