Hi :)
I'm new to gretl, and I'm from Poland so sorry for any language
misunderstandings.
Im currenty forecasting sales in my company and i'm using ARIMA with
regression. Sometimes, even if the model is well adjusted to the data,
when i try to get forecast for 3 months some of the values are below
0... what can i do to set a limit on that variable?
all the best for all gretl users!
Lukas
