Mass-shifting phenomenon of truncated multivariate normal priors
Shuang Zhou, Pallavi Ray, Debdeep Pati +1
We show that lower-dimensional marginal densities of dependent zero-mean normal distributions truncated to the positive orthant exhibit a mass-shifting phenomenon. Despite the trun…

Efficient Bayesian shape-restricted function estimation with constrained Gaussian process priors
Pallavi Ray, Debdeep Pati, Anirban Bhattacharya
This article revisits the problem of Bayesian shape-restricted inference in the light of a recently developed approximate Gaussian process that admits an equivalent formulation of…

Signal Adaptive Variable Selector for the Horseshoe Prior
Pallavi Ray, Anirban Bhattacharya
In this article, we propose a simple method to perform variable selection as a post model-fitting exercise using continuous shrinkage priors such as the popular horseshoe prior. Th…
