DOI: 10.1007/s11222-015-9622-1
Abstract: A pair of polychotomous random variables $$(Y_1,Y_2)^\top =:{\varvec{Y}}$$(Y1,Y2)⊤=:Y, where each $$Y_j$$Yj has a totally ordered support, is studied within a penalized generalized linear model framework. We deal with a triangular generating process for $${\varvec{Y}}$$Y, a… read more here.

DOI: 10.1177/0962280215610928
Abstract: We propose a Bayesian variable selection method in semi-parametric models with applications to genetic and epigenetic data (e.g., single nucleotide polymorphisms and DNA methylation, respectively). The data are individually standardized to reduce heterogeneity and facilitate… read more here.
