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 …
