WebBayes’ Theorem is often used in medicine to compute the probability of having a disease GIVEN a positive result on a diagnostic test. We will replace \(A\) and \(A^c\) in the previous formula with \(T^+\) and \(T^-\) (reprenting a positive and negative test result). We will also replace \(B\) with \(D^+\), representing having the disease. WebAnd it calculates that probability using Bayes' Theorem.

WebIn Bayesian analysis, A is a parameter or parameters we wish to estimate, and B is a set of data we have collected. Bayes’ theorem allows our prior ‘beliefs’ P(A) about the value of A to be updated by information from collected data B in terms of the likelihood P(B A), to give a posterior distribution P(A B).

WebMachine Learning is one of the technologies that help make the right decision at such times, and the Bayes Theorem helps make those conditional probability decisions better.
