This paper investigates misspecified estimation and model selection criteria derived from the 'Information Criterion (see Akaike (1973))' for qualitative choice models. Four estimators for the 'Information Criterion' are derived for general qualitative choice models. Two of these estimators were...

The use of large datasets for macroeconomic forecasting has received a great deal of interest recently. Boosting is one possible method of using high-dimensional data for this purpose. It is a stage-wise additive modelling procedure, which, in a linear specification, becomes a variable selection...

The large majority of the criteria for model selection are functions of the usual variance estimate for a regression model. The validity of the usual variance estimate depends on some assumptions, most critically the validity of the model being estimated. This is often violated in model...

En esta nota se realiza un estudio comparativo sobre dos criterios de selección de modelos no anidados, en concreto, el test J propuesto por Davidson y Mackinnon, y el test JA presentado por Fisher y McAleer. Mediante un ejercicio de simulación basado en un experimento de Monte Carlo se...

This paper studies the asymptotic relationship between Bayesian model averaging and post-selection frequentist predictors in both nested and nonnested models. We derive conditions under which their difference is of a smaller order of magnitude than the inverse of the square root of the sample...

This paper proposes neural network based measures of predictability in conditional mean, and then uses them to construct nonlinear analogues to autocorrelograms and partial autocorrelograms. In contrast to other measures of nonlinear dependence that rely on nonparametric estimation of densities...

Given that it is quite impractical to use standard model selection criteria in a nonlinear modeling context, the builders of nonlinear models often choose lag length by setting it equal to the lag length chosen for a linear autoregression of the data. This paper studies the performance of this...
