Effects of Proportional Hazard Assumption on Variable Selection Methods for Censored Data
STATISTICS IN BIOPHARMACEUTICAL RESEARCH, Vol. 12, pp. 199–209.
author keywords: AIDS trials; Crossing survival curves; Hazard regression; Penalized regression

MIMIX: A Bayesian Mixed-Effects Model for Microbiome Data From Designed Experiments
JOURNAL OF THE AMERICAN STATISTICAL ASSOCIATION.
author keywords: Continuous shrinkage prior; Factor analysis; Microbiome; Mixed model; Nutrient Network; OTU abundance data
TL;DR:
A novel Bayesian mixed-effects model that exploits cross-taxa correlations within the microbiome, a model the authors call microbiome mixed model (MIMIX), tailored to large microbiome experiments using a combination of Bayesian factor analysis to efficiently represent dependence between taxa and Bayesian variable selection methods to achieve sparsity.
