While we're at it, we may want to slightly revisit the behaviour of the TRAMO/SEATS backend for deseas(): if the automatic analysis finds no seasonality, then the seasonally adjusted series is simply not created and deseas() spits an error. Example: <hansl> open AWM18 catch series c = deseas(YER, T) err = $error printf "error %d: %s\n", err, errmsg(err) </hansl> gives <output> ? catch series c = deseas(YER, T) /home/jack/.gretl/tramo/graph/series/safin.t: No such file or directory ? err = $error Generated scalar err = 11 ? printf "error %d: %s\n", err, errmsg(err) error 11: Error attempting to open file </output> I guess that in this case we could just fill the seasnoally-adjusted series with the original values and issue a warning, but I'd rather ask you guys for your opinion. ------------------------------------------------------- Riccardo (Jack) Lucchetti Dipartimento di Scienze Economiche e Sociali (DiSES) Università Politecnica delle Marche (formerly known as Università di Ancona) r.lucchetti(a)univpm.it http://www2.econ.univpm.it/servizi/hpp/lucchetti -------------------------------------------------------
