Residual Analysis

Computes and analyzes the prediction error and correlation indices for the response output of a system model.

ParameterDescription
Prediction ErrorDisplays the waveform of the one-step-ahead prediction error of the response of the system.
Auto CorrelationDisplays the autocorrelation of Prediction Error.
Cross CorrelationDisplays the cross correlation of Prediction Error and Stimulus Signal.
InputsContains the following options:
  • Model—Specifies the system model to use for residual analysis.
  • Stimulus Signal—Specifies the stimulus input to apply to the model.
  • Response Signal—Specifies the output response from the model.
