I may confirm the bug with gretl in current cvs on Ubuntu Linux 10.04. I defined a dataset from 1837:12 to 2008:12 and a time trend, when compacting to annual the data was delimited to 1837-2007 (the last obs was that of 2007:12). By adding a new observation (/Data/Add observations..) the trend was correctly defined in 2009:01 but in compacting I continue to obtain the data only for 1837-2007. -- Ignacio Diaz-Emparanza DEPARTAMENTO DE ECONOMÍA APLICADA III (ECONOMETRÍA Y ESTADÍSTICA) UPV/EHU Avda.
