Support reverse chronological order in X-12-ARIMA
Most of my data is in reverse chronological order ie it starts with the latest value and goes down to the earliest. The website states that NumXL works with both orderings but that reverse chronological order needs to be specified. I can’t find how to specify this to the X12-ARIMA or perhaps it doesn’t matter to that function?

The X12ARIMA model is deprecated now!
The reverse chronological order is supported in the X13ARIMA-SEATS model.
