Thanks for the reply. (both of you) That is very helpful.
Unfortunately, I will not be able to share any of my numbers, as they
are not mine to share, but I'll be investigating a way to implement
ARIMA and intervention detection.

Do NOT implement first! First try to build model, using for example R or
other freely available software. You could also consider buying some
proprietary software. Implementing your own code is not the best
approach but as always it depends :)

Best regards

Thanks. I'll check those out. Are you advising I don't try to
implement because it's difficult, or because there is already good
software available?
Unfortunately, I do not have access to very sophisticated software
here, as my company expects me to stay within the bounds of Excel.

If you have any suggestions for introductory texts or software, please
let me know.

Sincerely,
N. Lee
