A Bayesian Multiple Testing Paradigm for Model Selection in Inverse Regression Problems

Debashis Chatterjee, Sourabh Bhattacharya

In this article, we propose a novel Bayesian multiple testing formulation for model and variable selection in inverse setups, judiciously embedding the idea of inverse reference di…

Convergence of Pseudo-Bayes Factors in Forward and Inverse Regression Problems

Debashis Chatterjee, Sourabh Bhattacharya

In the Bayesian literature on model comparison, Bayes factors play the leading role. In the classical statistical literature, model selection criteria are often devised used cross-…

Increasing Domain Infill Asymptotics for Stochastic Differential Equations Driven by Fractional Brownian Motion

Trisha Maitra, Sourabh Bhattacharya

Although statistical inference in stochastic differential equations (SDEs) driven by Wiener process has received significant attention in the literature, inference in those driven…

Posterior Consistency of Bayesian Inverse Regression and Inverse Reference Distributions

Debashis Chatterjee, Sourabh Bhattacharya

We consider Bayesian inference in inverse regression problems where the objective is to infer about unobserved covariates from observed responses and covariates. We establish poste…

Bayes Factor Asymptotics for Variable Selection in the Gaussian Process Framework

Minerva Mukhopadhyay, Sourabh Bhattacharya

Although variable selection is one of the most popular areas of modern statistical research, much of its development has taken place in the classical paradigm compared to the Bayes…

A Short Note on Almost Sure Convergence of Bayes Factors in the General Set-Up

Debashis Chatterjee, Trisha Maitra, Sourabh Bhattacharya

Although there is a significant literature on the asymptotic theory of Bayes factor, the set-ups considered are usually specialized and often involves independent and identically d…

Asymptotic Theory of Dependent Bayesian Multiple Testing Procedures Under Possible Model Misspecification

Noirrit K. Chandra, Sourabh Bhattacharya

We study asymptotic properties of Bayesian multiple testing procedures and provide sufficient conditions for strong consistency under general dependence structure. We also consider…

On Classical and Bayesian Asymptotics in Stochastic Differential Equations with Random Effects having Mixture Normal Distributions

Trisha Maitra, Sourabh Bhattacharya

Delattre et al. (2013) considered a system of stochastic differential equations (SDEs) in a random effects setup. Under the independent and identical (iid) situation, and assuming…

Bayes meet Riemann- Bayesian Characterization of Infinite Series with Application to Riemann Hypothesis

Sucharita Roy, Sourabh Bhattacharya

In the classical literature on infinite series there are various tests to determine if a given infinite series converges, diverges, or oscillates. But unfortunately, for very many…

Asymptotic Theory of Bayes Factor in Stochastic Differential Equations: Part I

Trisha Maitra, Sourabh Bhattacharya

Research on asymptotic model selection in the context of stochastic differential equations (SDEs) is almost non-existent in the literature. In particular, when a collection of SDEs…
