残差分析
使用白噪声和独立性测试分析残差
残差是基于模型的一步预测输出与基于验证数据集的测量输出之间的差异。换句话说，残差代表模型无法解释的验证数据部分。

- 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.
