モデルを推定した後に、それがシステム動作を許容限界内で再現するかどうかを検証できます。システム ダイナミクスを最も良く捉える最もシンプルなモデルが見つかるまで、モデルの微調整と検証を繰り返します。


Refine Linear Parametric Models

Procedures for refining model parameters after estimating a model or constructing the model with initial parameter guesses.

Refine Initial ARMAX Model at Command Line

This example shows how to estimate an initial model and refine it using pem.

Refine ARMAX Model with Initial Parameter Guesses at Command Line

This example shows how to refine models for which you have initial parameter guesses.


Validating Models After Estimation

Introduction to validating models and supported model plots.


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.
