P (E) /P (A); more generally, where E n is one of a set of values E i which partition the sample space, P (E n /A) = P (A/E n) P (E n) / Σ P (A/E i) P (E i). This enables prior estimates of probability to be continually revised in the light of observations Word Origin for Bayes' theoremC20: named after Thomas Bayes (1702–61), English mathematician and Presbyterian minister Collins English Dictionary - Complete & Unabridged 2012 Digital Edition © William Collins Sons & Co.
