System Identification Toolbox

The Validation Data

The two model views Model Output and Model Residuals illustrate model properties when applied to the Validation Data set. This is the set marked in the box below these two views. To change the Validation Data, drag and drop any data set from the Data Board on the Validation Data icon.

It is good and common practice in identification to evaluate an estimated model's properties using a "fresh" data set, that is, one that was not used for the estimation. It is thus good advice to let the Validation Data be different from the Working Data, but they should of course be compatible with these.
