Bayes' theorem applied to an event space generated by continuous random variables X and Y with known probability distributions. There exists an instance of Bayes' theorem for each point in the domain. In practice, these instances might be parametrized by writing the specified probability densities as a function of x and y.
In statistical classification, the Bayes classifier is the classifier having the smallest probability of misclassification of all classifiers using the same set of features. [ 1 ] Definition
The likelihood ratio is also of central importance in Bayesian inference, where it is known as the Bayes factor, and is used in Bayes' rule. Stated in terms of odds , Bayes' rule states that the posterior odds of two alternatives, A 1 {\displaystyle A_{1}} and A 2 {\displaystyle A_{2}} , given an event B {\displaystyle B ...
Bayes theorem visualisation: Image title: A geometric visualisation of Bayes' theorem by CMG Lee. The thumbnails denote the number of each corresponding condition and case, the probability being the fraction of each thumbnail that is shaded. Similar reasoning can be used to show that P(Ā|B) = P(B|Ā) P(Ā) / P(B) etc. Width: 100%: Height: 100%
Bayes' theorem describes the conditional probability of an event based on data as well as prior information or beliefs about the event or conditions related to the event. [3] [4] For example, in Bayesian inference, Bayes' theorem can be used to estimate the parameters of a probability distribution or statistical model. Since Bayesian statistics ...
English: Tree diagram illustrating "Simple example" for Bayes' theorem. R is the event that a beetle is rare. C is the event that a beetle is common. P is the event that a beetle has the pattern on its back. P bar is the event that a beetle does not have the pattern on its back.

Bayesian inference (/ ˈ b eɪ z i ə n / BAY-zee-ən or / ˈ b eɪ ʒ ən / BAY-zhən) [1] is a method of statistical 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.
