Selecting the Auxilary Order

The plot shows the fit as a function of the auxiliary order for the subspace state-space identification method N4SID.

The fit is the sum of squared prediction errors when evaluated for the model using the Working Data set. The sum is divided by the number of data.

The order corresponding to the lowest value of the fit - marked by a red bar - is automatically inserted into the Model board.
