Gibbs-sampling for modell-sammenligning

Gibbs-sampling for modell-sammenligning er en Bayesiansk MCMC-tilnærming som samtidig sampler fra rommet av konkurrerende modeller og deres parametere. Ved å utvide Gibbs-sampler med en diskret modell-indeks-variabel, estimeres posterior modell-sannsynligheter og Bayes-faktorer fra den resulterende Markov-kjeden uten å kreve separate kjøringer per modell.
