I mean, gretl needs to know that your observations are "time series" and what the seasonal periodicity of them is. Please have a look at the bottom line of the main window to see whether gretl is considering correctly your data. (For example if you go to /File/Open data/Sample/file and in the Ramanathan tab you select 'data9-3', this is a quarterly dataset and in the bottom line you may see "Quarterly: Full range 1972:2-1993:4"). If you have not correctly specified your dataset structure as a time series with seasonal periodicity > 1, the menu '/Add/Periodic dummies' should remain not active (grey). You may correct the structure of your dataset in the menu '/Data/Dataset structure...' -- Ignacio Díaz-Emparanza Departamento de Economía Aplicada III (Econometría y Estadística) Universidad del País Vasco - Euskalherriko Unibertsitatea, UPV/EHU Tfno: (+34) 94 601 3732 http://www.ehu.eus/ea3 _______________________________________________ Gretl-users mailing list Gretl-users(a)lists.wfu.edu http://lists.wfu.edu/mailman/listinfo/gretl-users
