MCMC til modelsammenligning

MCMC til modelsammenligning anvender Markov chain Monte Carlo-algoritmer til at estimere de marginale sandsynligheder og Bayes-faktorer, der er nødvendige for formelt at sammenligne konkurrerende statistiske modeller. Teknikker som reversible-jump MCMC og bridge sampling muliggør udforskning på tværs af modelrum af forskellig dimensionalitet, hvilket muliggør fuldt Bayesiansk modelvalg og -middelværdiberegning.
