Bayesian positive

Morphology

Bayesian = Bayes (transparent) = Bayes + ian

Formed by the regular adjectival suffix '-ian' from the proper name 'Bayes', meaning 'relating to Bayes' (i.e., Bayes' theorem or methods); morphologically regular though understanding requires domain knowledge.

Etymology

Bayesian comes from the name Bayes, after the English mathematician Thomas Bayes, and points to the rule called Bayes' theorem. That rule shows how to 'update' a 'probability' when you get new evidence, so a Bayesian method means you change your belief as you learn more.
