MCMC med manglende data

MCMC med manglende data er en Bayesiansk beregningsstrategi, der behandler uobserverede værdier som yderligere ukendte parametre. Ved at skifte mellem at sample de manglende værdier fra deres prædiktive fordeling og at sample modelparametrene fra deres posterior, producerer algoritmen en gyldig fælles posterior, der fuldt ud tager højde for usikkerheden introduceret af manglende data.
