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. On the way we introduce a new version of AIC for regression models, show that it estimates a …

In this paper we analyze the return of exchange rate in order to test and analyze the best models which are capable of forecasting accurately there evolution. We apply the GARCH family models on the exchange rate return in order to obtain the best models for there volatility. Financial time...

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...
