Blessing of dimension in Bayesian inference on covariance matrices
Shounak Chattopadhyay, Anru R. Zhang, David B. Dunson
Bayesian factor analysis is routinely used for dimensionality reduction in modeling of high-dimensional covariance matrices. Factor analytic decompositions express the covariance a…
Inferring Synergistic and Antagonistic Interactions in Mixtures of Exposures
Shounak Chattopadhyay, Stephanie M. Engel, David Dunson
There is abundant interest in assessing the joint effects of multiple exposures on human health. This is often referred to as the mixtures problem in environmental epidemiology and…
Nearest Neighbor Dirichlet Mixtures
Shounak Chattopadhyay, Antik Chakraborty, David B. Dunson
There is a rich literature on Bayesian methods for density estimation, which characterize the unknown density as a mixture of kernels. Such methods have advantages in terms of prov…
