The posterior probability is a type of conditional probability that results from updating the prior probability with information summarized by the likelihood...

the Bayesian probabilist specifies a prior probability. This, in turn, is then updated to a posterior probability in the light of new, relevant data (evidence)...

Probability is a branch of mathematics and statistics concerning events and numerical descriptions of how likely they are to occur. The probability of...

Laplace used conditional probability to formulate the relation of an updated posterior probability from a prior probability, given evidence. He reproduced...

word "probability" has been used in a variety of ways since it was first applied to the mathematical study of games of chance. Does probability measure...

rule, named by statistician Dennis Lindley, states that the use of prior probabilities of 1 ("the event will definitely occur") or 0 ("the event will definitely...

{\textstyle \theta } . That is, the relative probability assigned to a volume of a probability space using a Jeffreys prior will be the same regardless of the parameterization...

theory, algorithmic probability, also known as Solomonoff probability, is a mathematical method of assigning a prior probability to a given observation...

Frequentist probability or frequentism is an interpretation of probability; it defines an event's probability (the long-run probability) as the limit...

In probability theory, conditional probability is a measure of the probability of an event occurring, given that another event (by assumption, presumption...

sorts due to the general interest in Bayesian probability, because Bayesian methods require a prior probability distribution and the principle of indifference...

Inductive probability attempts to give the probability of future events based on past events. It is the basis for inductive reasoning, and gives the mathematical...

the prior probability distribution is estimated from the data. This approach stands in contrast to standard Bayesian methods, for which the prior distribution...

inference in which Bayes' theorem is used to calculate a probability of a hypothesis, given prior evidence, and update it as more information becomes available...

interpretation of probability, where probability expresses a degree of belief in an event. The degree of belief may be based on prior knowledge about the...
