Mixturmodellering

Mixturmodellering antager, at en population består af K uobserverede subpopulationer, der hver især beskrives af sin egen sandsynlighedsfordeling. De observerede data behandles som trækninger fra en vægtet kombination af disse komponentfordelinger. Det giver et principielt, modelbaseret alternativ til ad hoc-klyngning og understøtter formel sammenligning af løsninger med forskellige antal komponenter.
