Hi,
Through UI, just follow the menu path : Model/Time series/ARIMA and
specify the seasonal lag you need.
Otherwise, try to open gretl console and type in : /help arima/, to get
more information on arima command
Cheers,
artur

I am new to gretl and have been using the windows/UI version for a
couple of days now. Could someone help me understand how/where can I
specify the seasonal difference to be 3 or any number. The UI does not
allow me to specify a seasonal difference (lag) parameter (I am
assuming that it performs a 12 month seasonal difference when I
specify a seasonal ARIMA model by default).
