Non - Nested Model Selection / Validation : Making Credible Postsample Inference Feasible
Effective, credible inference with respect to the postsample forecasting performance of time series models is widely held to be infeasible. Consequently, the model selection and Granger-causality literatures have focussed almost exclusively on in-sample tests, which can easily be biased by typical specification-search activity. Indeed, the postsample error series generated by competing models a...

We also applaud CMAJ for publishing views that are more demanding and supportive of meaningful external verification of Canadian physicians’ ongoing competence than those of the Canadian Medical Association. We agree with much of what Levinson has advocated, specifically the call for a reval...

This study shows that the defi...
متن کاملCredible implementation
The theory of implementation abounds with mechanisms with intricate systems of rewards and punishments off-the-equilibrium path. Generally, it is not in the designer’s best interest to go through with the reward/punishment in the “subgame” arising from some disequilibrium play. This would make the mechanism’s outcome function non-credible. We define a notion of credible implementation and, in t...
