Dear all: I choose the monthly (or quarterly) data from1990 to 2008 for in-sample forecasting, 2009 to 2010 for out-of-sample forecasting. Finally, I find the ARIMA(1,1,1)(2,1,1) is the most appropriate model, then I want to use this model to forecast for 2011-2013. Can it generate forecasts for the future in Gretl? How to do this? Thanks a lot _______________________________________________ Gretl-users mailing list Gretl-users(a)lists.wfu.edu http://lists.wfu.edu/mailman/listinfo/gretl-users
