Bayesian Model Averaging

Bayesian Model Averaging (BMA), iliyofafanuliwa kama mafunzo na Hoeting, Madigan, Raftery na Volinsky mwaka 1999, hushughulikia kutokuwa na uhakika wa modeli kwa kuhesabu wastani wa vipimo vyote vinavyowezekana badala ya kuchagua modeli moja bora. Kila modeli inayoomba hupokea uwezekano wa baada ya ushahidi unaoonyesha jinsi inavyofaa data ikizingatiwa hali ya awali, na utabiri au makadirio ya mgawo huundwa kama wastani wenye uzito kutoka kwenye nafasi nzima ya modeli. Mbinu hii hupunguza upendeleo na kujiamini kupita kiasi kunakotokana na modeli moja iliyochaguliwa kutendewa kama ndiyo ya kweli.
