Section 3 establishes the BvM theorem for power posteriors and introduces the new approach to estimate the marginal likelihood. In Sec-tion 4, we compare the proposed method with the power-posterior method in terms of accuracy and computational e ciency using two examples. Section 5 concludes the paper. drl ljus

"WebThe BVM theorem is useful because it provides a frequentist justification for Bayesian inference. The main takeaway of the theorem is that Bayesian inference is asymptotically correct from a frequentist perspective. In particular, Bayesian credible intervals are asymptotically confidence intervals. " - Bvm theorem

Webthe BVM theorem constitutes a very suitable theoretical guarantee. The importance of this result lies in the fact that it gives the explicit asymptotic form of the rele-vant part of the posterior distribution, from which one easily derives in particular the consistency of the Bayes procedure, together with the fact that Bayesian conﬁdence
