 First of all, it seems that a hypothesis H is confirmed by new evidence E exactly when one’s credence in H ought to increase in response to the acquisition of E. Extending that idea, it also seems that how much H is confirmed correlates with how much its credence ought to be raised. With those ideas in mind, Bayesians have developed several accounts of confirmation; see  section 3 of the entry on confirmation.  Through the concept of confirmation, some Bayesians have also developed accounts of closely related concepts. For example, being supported by evidence seems to be the same as or similar to being confirmed by evidence, which is ultimately explained by Bayesians in terms of credence change. So there are some Bayesian accounts of evidential support; see  section 3 of the entry on Bayes’ theorem  and  sections 2.3–2.5 of the entry on imprecise probabilities.  Here is another example: how well a theory explains a body of evidence seems to be closely related to how well the theory is confirmed by the evidence, which is ultimately explained by Bayesians in terms of credence change. So there are some Bayesian accounts of explanatory power; see  section 2 of the entry on abduction.
