https://communities.sas.com/t5/SAS-Procedures/nonlinear-arima/m-p/67206#M19223 hi;<BR /> I am looking for SAS procedures that can help me fit nonlinear arima models. I could not yet find any.<BR /> can the ARIMA procedure be used to do so, with some settings? The normal ARIMA model is used to fit linear models, and not nonlinear. <BR /> <BR /> I have found different nonlinear models. like NLAR fingerprints, and nonlinear autoregressive with exogenous input. I am looking if a *nonlinear arima* exists to solve for parameters in these models.<BR /> <BR /> your help is appreciated.<BR /> thank U<BR /> <BR /> asmel.
