ARX time series models are a linear representation of a dynamic system in discrete time. Putting a model into ARX form is the basis for many methods in process ...

An ARX model is a combination of an autoregressive model (AR) and an exogenous input model (X). It is used to represent the dynamics of a system and is ...

A nonlinear ARX model consists of model regressors and an output function. The output function contains one or more mapping objects, one for each model output.

arx performs the estimation using a least-squares method and the polynomial orders specified in [na nb nk] . The model properties include covariances (parameter ...

However, the ARX model captures some of the stochastic dynamics as part of the system dynamics. In this model, the transfer function of the deterministic part G ...
