Multi-Step/One-Step Ahead Prediction

The mechanism of the NARX model prediction can be changed between one-step and multi-step ahead prediction (Model > NARX Model Options > One Step Ahead Prediction / Multi Step Ahead Prediction).

Note
The important difference is that the multi-step ahead prediction uses past model predictions within the feedback (NARX) structure instead of the measured values (see Model structure for nonlinear autoregression with exogenous inputs (NARX)). Multi-step ahead prediction is the standard setting and corresponds to a real offline simulation, where no system responses are available during model prediction.
