Robust and Accurate Inference via a Mixture of Gaussian and Student's t Errors
JOURNAL OF COMPUTATIONAL AND GRAPHICAL STATISTICS, 28(2), 415–426.
author keywords: Gaussian process; Gibbs sampling; Hierarchical model; Huber's M-estimator; Linear mixed model; Outlier; Time series
TL;DR:
A mixture error assumption is proposed that selectively converts Gaussian errors into Student's t errors according to latent outlier indicators, leveraging the best of the Gaussian and Student’s t errors; a parameter estimation can be not only robust but also accurate.

TL;DR:
This work considers rejecting the null hypothesis, in favor of the alternative, when a test statistic exceeds a cutoff, and chooses the cutoff to minimize a weighted sum of Bayesian average errors and the sample size to bound the total error for the hypothesis test.

Major gene detection for fusiform rust resistance using Bayesian complex segregation analysis in loblolly pine
THEORETICAL AND APPLIED GENETICS, 113(5), 921–929.
Contributors: H. Li n, n , H. Amerson n & B. Li n
MeSH headings : Basidiomycota / pathogenicity; Bayes Theorem; Chromosome Mapping; Chromosome Segregation; Genes, Plant; Genotype; Immunity, Innate / genetics; Inheritance Patterns / genetics; Models, Genetic; Phenotype; Pinus taeda / genetics; Pinus taeda / growth & development; Pinus taeda / microbiology; Plant Diseases / genetics; Plant Diseases / microbiology
TL;DR:
It appears that there may be two or more major genes affecting disease phenotypes in this diallel population of loblolly pine, and the MIM was a better model to explain the inheritance of rust resistance than the pure PM in the dialleL population.

A physiologically‐based pharmacokinetic (PBPK) model to quantify the internal, target‐tissue dosimetry of genistein in adult rats is developed and can serve as a template for other phytoestrogens and in the design of future experiments and research that can be used to fill data gaps and better estimate model parameters.

TL;DR:
A multivariate spatial regression model is developed for the estimation of the risk of mortality associated with fine PM and its components across all counties in the conterminous United States and shows that in the Western United States, the nitrate and crustal components of the speciated fine PM seem to have more impact on mortality than the other components.

Proportional hazards models: a latent competing risk approach
JOURNAL OF THE ROYAL STATISTICAL SOCIETY SERIES C-APPLIED STATISTICS, 49(3), 385–397.
Contributors: A. Gelfand *, n , C. Christiansen *, S. Soumerai * & T. McLaughlin*
author keywords: censoring; competing risk; data augmentation; semiparametric regression
TL;DR:
A novel semiparametric version of the widely used proportional hazards survival model, featuring an arbitrarily rich class of continuous base‐line hazards, an attractive epidemiological interpretation of the hazard as a latent competing risk model and trivial handling of censoring is proposed.
