WebA Bayes Factor reflects how likely data is to arise from one model, compared to another model. Typically, one of the models is the null model (H0): a model that predicts that your … 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.

WebWhere the likelihood ratio (the middle term) is the Bayes factor - it is the factor by which some prior odds have been updated after observing the data to posterior odds. Thus, Bayes factors can be calculated in two ways: As a ratio quantifying the relative probability of the observed data under each of the two models.
