Adaptive posterior contraction rates for the horseshoe [PDF]

open access: yes, 2017
We investigate the frequentist properties of Bayesian procedures for estimation based on the horseshoe prior in the sparse multivariate normal means model.

A statistical framework for joint eQTL analysis in multiple tissues [PDF]

open access: yes, 2012
Mapping expression Quantitative Trait Loci (eQTLs) represents a powerful and widely-adopted approach to identifying putative regulatory variants and linking them to specific genes.

On the half-Cauchy prior for a global scale parameter [PDF]

open access: yes, 2010
This paper argues that the half-Cauchy distribution should replace the inverse-Gamma distribution as a default prior for a top-level scale parameter in Bayesian hierarchical models, at least for cases where a proper prior is necessary.

Sparse Portfolio selection via Bayesian Multiple testing

open access: yes, 2020
We presented Bayesian portfolio selection strategy, via the $k$ factor asset pricing model. If the market is information efficient, the proposed strategy will mimic the market; otherwise, the strategy will outperform the market.

Bayesian Model Comparison in Genetic Association Analysis: Linear Mixed Modeling and SNP Set Testing [PDF]

open access: yes, 2015
We consider the problems of hypothesis testing and model comparison under a flexible Bayesian linear regression model whose formulation is closely connected with the linear mixed effect model and the parametric models for SNP set analysis in genetic ...

Minimax Structured Normal Means Inference

open access: yes, 2016
We provide a unified treatment of a broad class of noisy structure recovery problems, known as structured normal means problems. In this setting, the goal is to identify, from a finite collection of Gaussian distributions with different means, the ...

Hierarchical Bayes prediction for the 2008 US Presidential election [PDF]

open access: yes
In this paper a procedure is developed to derive the predictive density function of a future observation for prediction in a multiple regression model under hierarchical priors for the vector parameter.

Bayes factors and the geometry of discrete hierarchical loglinear models

open access: yes, 2011
A standard tool for model selection in a Bayesian framework is the Bayes factor which compares the marginal likelihood of the data under two given different models.
