Conceptos básicos de la validación de modelos
Después de estimar un modelo, puede validar si reproduce el comportamiento del sistema dentro de límites aceptables. Luego, puede iterar entre el perfeccionamiento y la validación del modelo hasta que encuentre el modelo más sencillo que capture mejor la dinámica del sistema.

Resolve Fit Value Differences Between Model Identification and compare Command
This example shows how NRMSE fit values computed by model identification functions and by the compare function can differ because of differences in initial conditions and prediction horizon settings.
