Dear all,
when I try to forecast a variable with an equation that has that variable in differentiated form say, d(mwh) ar(1) sar(12) ma(12), the graphical interface offers two alternatives for the forecasted series: d(mwh) or mwh.
How can I program that option in script form?
Thanks,
Mario

From the object reference:

Thank you for your prompt answer.
However, I will have to double check wheteher the error (rmse, mape, mae, etc...) results are correctly calculated; initially it appears something is amiss.
Yours,
Mario
