In this article, we analyze the efficiency of Brazilian local legislative branches using the nonparametric estimator FDH (Free Disposal Hull). At the regional level, the results show high concentration of local legislative branches in the south. In addition, among the inefficient local...

We study model selection strategies based on penalized empirical loss minimization. We point out a tight relationship between error estimation and data-based complexity penalization: any good error estimate may be converted into a data-based penalty function and the performance of the estimate...
