Web10 de nov. de 2005 · 1. Introduction. Bayes factors are the corner-stone of Bayesian hypothesis testing (e.g. Jeffreys (1961)).In contrast with classical p-values, the value of a Bayes factor has a direct interpretation in terms of whether or not a hypothesis is true: it represents the factor by which data modify the prior odds of two hypotheses to give the … Web20 de mar. de 2024 · To extract useful information about the SOEQ from a p-value, we would ideally translate a p-value into a Bayes factor. Unfortunately, there is no unique mapping between p -values and Bayes factors because, unlike calculating the p -value, calculating the Bayes factor requires specifying an alternative hypothesis (more …
