Model Validation Basics

Ways to validate models, refine models, troubleshooting

After estimating a model, you can validate whether it reproduces the system behavior within acceptable bounds. Iterate between model refinement and validation until you find the simplest model that best captures the system dynamics.

Examples and How To



Troubleshooting Model Estimation

Adjust your modeling strategy based on model-validation results.

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.
