  • linear systems - Estimate a Transfer Function from ARX .

    There is the top down method of hendry, the schwert criterion, AIC etc. Luktepohl's text probably discusses model selection in these types of models but focuses on AR and ARI and not so much the MA terms. Also, it sounds like the response y_t is a scalar but, in case it isn't, you want to look at VARS which luktepohl covers in great detail.

  • ARX Model Definitions (System Identification Toolkit .

    ARX Model Definitions (System Identification Toolkit) . the general-linear polynomial model reduces to an autoregressive with exogenous terms (ARX) model. This model is the simplest model that incorporates the stimulus signal. However, the ARX model captures some of the stochastic dynamics as part of the system dynamics.

  • Estimate parameters of ARMAX model using time-domain data .

    If init_sys is not a polynomial model of ARMAX structure, the software first converts init_sys to an ARMAX model. armax uses the parameters of the resulting model as the initial guess for estimating sys. If opt is not specified, and init_sys was obtained by estimation, then the estimation options from init_sys.Report.OptionsUsed are used.
