World English Dictionary
Bayes' theorem (beɪz)
 
n
statistics the fundamental result which expresses the conditional probability P(E/A) of an event E given an event A as P(A/E).P(E)/P(A); more generally, where En is one of a set of values Ei which partition the sample space, P(En/A) = P(A/En)P(En)/Σ P(A/Ei)P(Ei). This enables prior estimates of probability to be continually revised in the light of observations
 
[C20: named after Thomas Bayes (1702--61), English mathematician and Presbyterian minister]
