"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.

The Bayes factor is a ratio of two competing statistical models represented by their evidence, and is used to quantify the support for one model over the other. The models in questions can have a common set of parameters, such as a null hypothesis and an alternative, but this is not necessary; for instance, it could also be a non-linear model compared to its linear approximation.
