In …Most traditional strategies of assessing the fit between a simulation's set of predictions (outputs) and a set of … relevant observations rely either on visual inspection or squared distances among averages. Here we introduce an alternative …

We derive the asymptotic theory of the maximum likelihood estimators and show they are consistent and asymptotically … comparisons of a consistent version of our $C_{p}$ statistic with BIC and a generalized RIC show that our statistic has superior … about the choice of model.

The proportion of zeros in event-count processes may be inflated by an additional mechanism by which zeros are created. This has given rise to statistical models that accommodate zero inflation; these are available in Stata through the zip and zinb commands. The Vuong (1989, Econometrica 57:...

L'utilisation des chaînes de Markov d'ordre supérieur à 1 est généralement difficile, particulièrement lorsque le nombre de données à disposition est petit. L'approche envisagée ici, proposée pour la première fois par Raftery, consiste à approximer ces chaînes à l'aide d'un modèle...
