Price discovered Bayes's work, recognized its importance, corrected it, contributed to the article, and found a use for it. Martyn Hooper and Sharon McGrayne have argued that Richard Price's contribution was substantial:īy modern standards, we should refer to the Bayes–Price rule. Stephen Stigler used a Bayesian argument to conclude that Bayes' theorem was discovered by Nicholas Saunderson, a blind English mathematician, some time before Bayes that interpretation, however, has been disputed. Ībout 200 years later, Sir Harold Jeffreys put Bayes's algorithm and Laplace's formulation on an axiomatic basis, writing in a 1973 book that Bayes' theorem "is to the theory of probability what the Pythagorean theorem is to geometry". The Bayesian interpretation of probability was developed mainly by Laplace. He reproduced and extended Bayes's results in 1774, apparently unaware of Bayes's work. Independently of Bayes, Pierre-Simon Laplace in 1774, and later in his 1812 Théorie analytique des probabilités, used conditional probability to formulate the relation of an updated posterior probability from a prior probability, given evidence. On 27 April a letter sent to his friend Benjamin Franklin was read out at the Royal Society, and later published, where Price applies this work to population and computing 'life-annuities'. In 1765, Price was elected a Fellow of the Royal Society in recognition of his work on the legacy of Bayes. Price wrote an introduction to the paper which provides some of the philosophical basis of Bayesian statistics and chose one of the two solutions offered by Bayes. Price edited Bayes's major work "An Essay towards solving a Problem in the Doctrine of Chances" (1763), which appeared in Philosophical Transactions, and contains Bayes' theorem. Over two years, Richard Price significantly edited the unpublished manuscript, before sending it to a friend who read it aloud at the Royal Society on 23 December 1763. On Bayes's death his family transferred his papers to a friend, the minister, philosopher, and mathematician Richard Price. Bayes studied how to compute a distribution for the probability parameter of a binomial distribution (in modern terminology). His work was published in 1763 as An Essay towards solving a Problem in the Doctrine of Chances. Bayes used conditional probability to provide an algorithm (his Proposition 9) that uses evidence to calculate limits on an unknown parameter. Bayesian inference is fundamental to Bayesian statistics, being considered by one authority as "to the theory of probability what Pythagoras's theorem is to geometry." History īayes' theorem is named after the Reverend Thomas Bayes ( / b eɪ z/), also a statistician and philosopher. ![]() With Bayesian probability interpretation, the theorem expresses how a degree of belief, expressed as a probability, should rationally change to account for the availability of related evidence. When applied, the probabilities involved in the theorem may have different probability interpretations. One of the many applications of Bayes' theorem is Bayesian inference, a particular approach to statistical inference. For example, if the risk of developing health problems is known to increase with age, Bayes' theorem allows the risk to an individual of a known age to be assessed more accurately by conditioning it relative to their age, rather than simply assuming that the individual is typical of the population as a whole. 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 event.
