I have a use case where I want to forecast the performance of one store using the historical performance of another store. For example, store A has 3 years of performance data and I noticed store B has similar demographics. I figure I can “train” an ARIMA model on store A and then fit the model to forecast the performance of store B. Has anybody done this before? I would like to display it in workshop so I can parameterize the stores and do this on the fly without needing transforms and such.
