- Probability of a hypothesis given observed evidencePosterior probability is a fundamental concept in Bayesian statistics, representing the probability of a hypothesis given observed evidence. It is derived from Bayes’ theorem, which mathematically expresses how to update the probability of a hypothesis as more evidence becomes available.

The posterior probability is a type of conditional probability that results from updating the prior probability with information summarized by the likelihood via an application of Bayes' rule. From an epistemological perspective, the posterior probability contains everything there is to know about an … See more
