Recomendaciones para Seleccionar Índices para la Validación de Modelos

A set of recommendations to select error indices to model validation is presented in this paper. The recommendations are based on the comparison of indices used to validate dynamic systems. Nine error indices and one fit index are presented and mathematically defined. Based on the data reported in literature to validate models, step function and sine function are selected, as patron signals, to evaluate the index results. As a relevant contribution of this paper, recommendations to select and interpret error indices during the validation of physical system models are given.
