Hello,

 

I have a Forecast Studio project with a weekly time scale and thus the seasonal cycle length is 52. I've noticed that when I add an event to a copy of an automatically generated Subset ARIMA model that has DIF = (1 52), the event is then assigned DIF = (53). All of the other events that have been automatically included in the model have the same differencing as the model, i.e. DIF = (1 52). To the best of my knowledge, an event's differencing should be the same as the model's differencing. Is there an explanation as to why it assigns DIF = (53) instead of (1 52)?

 

Thanks,

Blake
