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 …

Web29 de jul. de 2014 · The approach illustrated in this paper has lifted the Bayes factor out of that context and treated it alone as a measure of strength of evidence (cf. Royall, 1997; Rouder et al., 2009). So there is no need to specify that sort of prior. But the Bayes factor itself requires specifying what the theories predict, and this is also called a prior.
