Fig. 2. Bayes theorem. Panel 'a' shows all the terms of Bayes' theorem. (a) is read 'the probability of the model given the data', and refers to the posterior probability. (b) is the likelihood, and is read 'the probability of the data given the model'. (c) is the prior probability of the model. (d) is the marginal probability of the data. Panel 'b' shows the same equation, but with which terms are model assumptions and which terms are observed data annotated.
