Automatic (Time Rolling) forecasting in a program

Postby rachanon.c » Wed Jun 05, 2024 8:12 am

What are the first 7 lines of the program for - what are they meant to do?

I'm not really sure what your program is doing, so hard to pin point any issues. The first 7 lines don't make sense (or, aren't needed). The forecast lines outside of the loop doesn't make sense to me either.

Okay from your help, I think my first 7 lines aren't needed. I want to make equation that loop forecast step by step ahead 4 Quarter and keep series in forecast series to compare. Maybe I am programming wrong from begin.
