bridgesampling: An R Package for Estimating Normalizing Constants

Subject

bridge sampling, marginal likelihood, model selection, Bayes factor, Warp-III

Description

Statistical procedures such as Bayes factor model selection and Bayesian model averaging require the computation of normalizing constants (e.g., marginal likelihoods). These
normalizing constants are notoriously difficult to obtain, as they usually involve highdimensional integrals that cannot be solved analytically. Here we introduce an R package
that uses bridge sampling (Meng and Wong 1996; Meng and Schilling 2002) to estimate
normalizing constants in a generic and easy-to-use fashion. For models implemented in
Stan, the estimation procedure is automatic. We illustrate the functionality of the package
with three examples.
