A novel sandwich algorithm for empirical Bayes analysis of rank data
Arnab Kumar Laha, Somak Dutta, Vivekananda Roy
Rank data arises frequently in marketing, finance, organizational behavior, and psychology. Most analysis of rank data reported in the literature assumes the presence of one or mor…
Analysis of the Polya-Gamma block Gibbs sampler for Bayesian logistic linear mixed models
Xin Wang, Vivekananda Roy
In this article, we construct a two-block Gibbs sampler using Polson et al. (2013) data augmentation technique with Polya-Gamma latent variables for Bayesian logistic linear mixed…
A note on marginal correlation based screening
Run Wang, Somak Dutta, Vivekananda Roy
Independence screening methods such as the two sample -test and the marginal correlation based ranking are among the most widely used techniques for variable selection in ultrah…
Convergence analysis of the block Gibbs sampler for Bayesian probit linear mixed models with improper priors
Xin Wang, Vivekananda Roy
In this article, we consider Markov chain Monte Carlo(MCMC) algorithms for exploring the intractable posterior density associated with Bayesian probit linear mixed models under imp…
