WebBayesian inference is a way of making statistical inferences in which the statistician assigns subjective probabilities to the distributions that could generate the data. These subjective probabilities form the so-called prior distribution. Bayes' theorem is stated mathematically as the following equation: where $${\displaystyle A}$$ and $${\displaystyle B}$$ are events and $${\displaystyle P(B)\neq 0}$$. $${\displaystyle P(A\mid B)}$$ is a conditional probability: the probability of event $${\displaystyle A}$$ occurring given that … See more In probability theory and statistics, Bayes' theorem (alternatively Bayes' law or Bayes' rule), named after Thomas Bayes, describes the probability of an event, based on prior knowledge of conditions that might be related to the … See more Bayes' theorem is named after the Reverend Thomas Bayes (/beɪz/), also a statistician and philosopher.
