Bayes Minimax Competitors of Preliminary Test Estimators in k Sample Problems
Ryo Imai, Tatsuya Kubokawa, Malay Ghosh
In this paper, we consider the estimation of a mean vector of a multivariate normal population where the mean vector is suspected to be nearly equal to mean vectors of other…
Bayesian Simultaneous Estimation for Means in Sample Problems
Ryo Imai, Tatsuya Kubokawa, Malay Ghosh
This paper is concerned with the simultaneous estimation of population means when one suspects that the means are nearly equal. As an alternative to the preliminary test es…
The Inverse Gamma-Gamma Prior for Optimal Posterior Contraction and Multiple Hypothesis Testing
Ray Bai, Malay Ghosh
We study the well-known problem of estimating a sparse -dimensional unknown mean vector with entries corrupted by Gaussian white noise. In the Bayesian fram…
High-dimensional posterior consistency for hierarchical non-local priors in regression
Xuan Cao, Kshitij Khare, Malay Ghosh
The choice of tuning parameters in Bayesian variable selection is a critical problem in modern statistics. In particular, for Bayesian linear regression with non-local priors, the…
