Only a comment about "filter": I am using this command now and I think it is not very consistent with the present behaviour of the rest of the gretl commands to use the default value of y0=0 when y0 is not given by the user. It would be better to do y0=NA by default. -- Ignacio Diaz-Emparanza DEPARTAMENTO DE ECONOMÍA APLICADA III (ECONOMETRÍA Y ESTADÍSTICA) UPV/EHU Avda.
