Gibbs-sampling med manglende data

Gibbs-sampling med manglende data behandler uobserverte verdier som ytterligere ukjente sammen med modellparametere og sampler alle disse samlet innenfor en Markov chain Monte Carlo-løkke. Metoden veksler mellom å trekke de manglende verdiene fra deres betingede fordeling gitt parameterne og å trekke parameterne fra deres betingede fordeling gitt de fullstendige dataene, og produserer dermed en posterior for begge samtidig.
