A note on simulation methods for the Dirichlet-Laplace prior

Luis Gruber, Gregor Kastner, Anirban Bhattacharya +3

Bhattacharya et al. (2015, Journal of the American Statistical Association 110(512): 1479-1490) introduce a novel prior, the Dirichlet-Laplace (DL) prior, and propose a Markov chai…

A Hybrid Approximation to the Marginal Likelihood

Eric Chuu, Debdeep Pati, Anirban Bhattacharya

Computing the marginal likelihood or evidence is one of the core challenges in Bayesian analysis. While there are many established methods for estimating this quantity, they predom…

Approximate Laplace approximations for scalable model selection

David Rossell, Oriol Abril, Anirban Bhattacharya

We propose the approximate Laplace approximation (ALA) to evaluate integrated likelihoods, a bottleneck in Bayesian model selection. The Laplace approximation (LA) is a popular too…

The Soft Multivariate Truncated Normal Distribution with Applications to Bayesian Constrained Estimation

Allyson Souris, Anirban Bhattacharya, Debdeep Pati

We propose a new distribution, called the soft tMVN distribution, which provides a smooth approximation to the truncated multivariate normal (tMVN) distribution with linear constra…

Bayes Shrinkage at GWAS scale: Convergence and Approximation Theory of a Scalable MCMC Algorithm for the Horseshoe Prior

James E. Johndrow, Paulo Orenstein, Anirban Bhattacharya

The horseshoe prior is frequently employed in Bayesian analysis of high-dimensional models, and has been shown to achieve minimax optimal risk properties when the truth is sparse.…

Fast sampling with Gaussian scale-mixture priors in high-dimensional regression

Anirban Bhattacharya, Antik Chakraborty, Bani K. Mallick

We propose an efficient way to sample from a class of structured multivariate Gaussian distributions which routinely arise as conditional posteriors of model parameters that are as…
