Bayesian regularization for flexible baseline hazard functions in Cox survival models
Elena Lázaro, Carmen Armero, Danilo Alvares
Fully Bayesian methods for Cox models specify a model for the baseline hazard function. Parametric approaches generally provide monotone estimations. Semi-parametric choices allow…

Bayes factors for longitudinal model assessment via power posteriors
Gabriel Calvo, Carmen Armero, Luigi Spezia +1
Bayes factor, defined as the ratio of the marginal likelihood functions of two competing models, is the natural Bayesian procedure for model selection. Marginal likelihoods are usu…

Bayesian joint models for longitudinal and survival data
Carmen Armero
This paper takes a quick look at Bayesian joint models (BJM) for longitudinal and survival data. A general formulation for BJM is examined in terms of the sampling distribution of…
