The posterior probability is a type of conditional probability that results from updating the prior probability with information summarized by the likelihood, through an application of Bayes' theorem. From an epistemological perspective, the posterior probability contains everything there is to know about an uncertain proposition (such as a scientific hypothesis, or parameter values), given prior knowledge and a mathematical model describing the observations available at a particular time.
