Abstract
The estimation of the regression function, can analyze a transformation of this function. The option for this transformation is grounded by the economic analysis which defines the parameters of interest. A procedure of adjustment is included, consisting of the elimination of the data placed at the limit of the support of the explanatory variables distribution. The adjustment can be inserted in the function as the form of a function with multiplying indicator.
