I just wanted to find out if there is an ARIMA model with "external regressors" available. I wanted to check if promotions can be entered as "external regressors" on top of the current seasonal ARIMA model.
The ARIMA tool does allow for the use of covariates in developing a TS model (ARIMAX). The option can be found in the tool's configuration under the Required Parameters
Additionally, if you are using covariates to build an ARIMA model object, you will want to use the TS Covariate Forecast tool in order to generate your forecasts:
One last resource that is pretty helpful when using the Alteryx TS tools is the the online book Forecasting: Principles and Practice, which is co-written by Rob Hyndman, who is also the author of the forecast package which is used for these tools.
