Stat Sin
. 2018 Apr;
28(2):1053-1078.
PMID: 29643721
Bayesian model selection procedures based on nonlocal alternative prior densities are extended to ultrahigh dimensional settings and compared to other variable selection procedures using precision-recall curves. Variable selection procedures included...

. 2018 Jan;
45(1):1-38.
PMID: 29332971
Contingency table analysis routinely relies on log-linear models, with latent structure analysis providing a common alternative. Latent structure models lead to a reduced rank tensor factorization of the probability mass...

Biometrika
. 2017 Apr;
103(4):985-991.
PMID: 28435166
We propose an efficient way to sample from a class of structured multivariate Gaussian distributions. The proposed algorithm only requires matrix multiplications and linear system solutions. Its computational complexity grows...

. 2016 Mar;
110(512):1479-1490.
PMID: 27019543
Penalized regression methods, such as regularization, are routinely used in high-dimensional applications, and there is a rich literature on optimality properties under sparsity assumptions. In the Bayesian paradigm, sparsity is...

. 2015 Sep;
72(1):184-92.
PMID: 26394204
It is common in biomedical research to run case-control studies involving high-dimensional predictors, with the main goal being detection of the sparse subset of predictors having a significant association with...

. 2015 Feb;
133(6):815-27.
PMID: 25712548
In the sustained presence of agonist, the opening of P2X7R channel is followed by pore dilatation, which causes an increase in its permeability to larger organic cations, accompanied by receptor...

Ann Stat
. 2014 Oct;
42(1):352-381.
PMID: 25288827
In nonparametric regression problems involving multiple predictors, there is typically interest in estimating an anisotropic multivariate regression surface in the important predictors while discarding the unimportant ones. Our focus is...

J Am Stat Assoc
. 2013 Aug;
107(497):362-377.
PMID: 23908561
Gaussian latent factor models are routinely used for modeling of dependence in continuous, binary, and ordered categorical data. For unordered categorical variables, Gaussian latent factor models lead to challenging computation...

PMID: 23637193
The hypothalamic suprachiasmatic nuclei (SCN), the circadian master clock in mammals, releases ATP in a rhythm, but the role of extracellular ATP in the SCN is still unknown. In this...
