Abstract

Statisticians continue trying to model real phenomenon. Linear models are a powerful tool even when the true unknown model is non linear, because they bring us good approximations. We propose a model selection strategy sensible to apply in situation where we have a unique regressor which is a qualitative one. The strategy seems to be a modification of one proposed by Castells (1999) (see also Bunke y Castells, 1999). A validation in terms of simulated data is presented. [ABSTRACT FROM AUTHOR]
