Análisis de valores residuales

Analice valores residuales utilizando pruebas de blancura e independencia

Los valores residuales son diferencias entre la salida prevista a un paso por adelantado por un modelo y la salida medida del conjunto de datos de validación. Dicho de otra forma, los valores residuales representan la parte de los datos de validación no explicada por el modelo.

Funciones

`pe`	Prediction error for identified model
`peOptions`	Option set for `pe`

What Is Residual Analysis?
Residuals are differences between the one-step-ahead predicted output from the model and the measured output from the validation data set.
How to Plot Residuals in the App
Create a residual analysis plot for linear and nonlinear models in the System Identification app.
How to Plot Residuals at the Command Line
Create a residual-analysis plot for linear and nonlinear models at the command line.
Examine Model Residuals
This example shows how you can use residual analysis to evaluate model quality.
