Model specification and selection are recurring themes in econometric analysis. Both topics become considerably more complicated in the case of large-dimensional data sets where the set of specification possibilities can become quite large. In the context of linear regression models, penalised...

could benefit from the cross-fertilization spatial data mining techniques such as Classification and Regression Trees (CART …). We use the CART algorithm to fit empirical data and produce a tree with optimal tree size for different specifications of …-residuals obtained from the regression tree analysis and we compare the accuracy and performance of different versions of CART that take …

We review key aspects of forecasting using nonlinear models. Because economic models are typically misspecified, the resulting forecasts provide only an approximation to the best possible forecast. Although it is in principle possible to obtain superior approximations to the optimal forecast...
