In the design of ecient simulation algorithms, one is often beset with a poorchoice of proposal distributions. Although the performances of a given kernel canclarify how adequate it is for the problem at hand, a permanent on-line modicationof kernels causes concerns about the validity of the...

The deviance information criterion (DIC) introduced by Spiegelhalteret al. (2002) is directly inspired by linear and generalised linear models,but it is not so naturally dened for missing data models. In this paper,we reassess the criterion for such models, testing the behaviour of...
