Line 1:
In [[time series]] modeling, a '''nonlinear autoregressive exogenous model''' (NARX) is a [[nonlinear]]{{disambiguation needed|date=April 2024}} [[autoregressive model]] which has [[exogenous]] inputs. This means that the model relates the current value of a time series to both:
* past values of the same series; and
* current and past values of the driving (exogenous) series — that is, of the externally determined series that influences the series of interest.
