In this paper was evaluated several methods of inference about income convergence hypothesis exploring the database of Brazilian northeast municipalities through the 1970-1996. The results show that linear quantile regression does not capture the divergences between quantilic curves that characterize the formation of convergence clubs, although its use can solve many difficulties into least squares fitting. In this direction, this study applies nonparametric quantile regression know as quantile smoothing splines. We can conclude to that period that northeast municipalities are better characterized by clubs convergence formation.
