The theorem was discovered among the papers of the English Presbyterian minister and mathematician Thomas Bayes and published posthumously in 1763. Bayes' Theorem is a simple mathematical formula used for calculating conditional probabilities. It figures prominently in subjectivist or Bayesian approaches to epistemology, statistics, and inductive logic. Subjectivists, who maintain that rational belief is governed by the laws of probability, lean heavily on conditional probabilities in their theories of evidence and their models of empirical learning. Bayes’ Theorem is based on a thought experiment and then a demonstration using the simplest of means. Reverend Bayes wanted to determine the probability of a future event based on the number of times it occurred in the past. It’s hard to contemplate how to accomplish this task with any accuracy.

Bayes' theorem is to recognize that we are dealing with sequential events, whereby new additional information is obtained for a subsequent event, and that new information is used to revise the probability of the initial event.

Men även inom Thomas Bayes teorem kan med redan kända fakta förutse och tycker att det är en bra idé att använda teoremet också för att stoppa spam. Sekventiell användning av Bayes teorem presenteras och dess fördelar illustreras genom att beräkna uppdateringar som bygger på ett växande antal Vad är Bayes sats? Bayes teorem, som ibland kallas Bayes regel eller principen om omvänd sannolikhet, är en matematisk sats som följer igår kommer de kanske att skylla det på politisk dumhet och – kanske – matematisk okunnighet, närmare bestämt okunnighet i Bayes teorem.

For example, you can: Correct for measurement errors. If you know the real probabilities and the chance of a false positive and false negative, you can correct for measurement errors. Bayes' theorem is to recognize that we are dealing with sequential events, whereby new additional information is obtained for a subsequent event, and that new information is used to revise the probability of the initial event.

En sannolikhetsteoretisk modell uppkallad efter Thomas Bayes (1702-1761). Inom epidemiologin används metoden för beräkning av sannolikheten för förekomsten av en viss sjukdom hos personer med något visst kännetecken, utifrån kännedom om sjukdomens prevalens och förekomsten av detta kännetecken hos friska och sjuka individer.
