The system identification process leads to an inevitable final step of validation of the models obtained, a task that requires the accumulated experience of the investigator. With the aim of improving the process it is carried out this work, described below, in which a graphical interface capable of calculating and displaying numerical criteria that measure the goodness of fit, to support the selection process developed Mean squares residual (or error), Akaike information
Criterion, Bayesian information Criterion and coefficient of determination: identified, such as structures. Furthermore tests conducted to validate the effectiveness of the interface are described, showing very good results in performance. Tests were performed with real data, obtained from a flocculation process wastewater treatment plant refinery le «Camilo Cienfuegos» in the city of Cienfuegos, Cuba.
