Bayesiansk probitmodel

Den Bayesianske probitmodel er en binær regressionsmetode, der modellerer sandsynligheden for et binært udfald ved hjælp af den normale CDF (probit-link) inden for et Bayesiansk rammeværk. Den tildeler prior-fordelinger til regressionskoefficienter og opdaterer dem med observerede data, hvilket resulterer i en fuld posterior-fordeling snarere end et enkelt punktestimat. Albert-Chib's data-augmenteringsalgoritme gør posterior-sampling beregningsmæssigt effektiv via Gibbs-sampling.
