Hi all, the next gretl version is going to be released in a matter of days, and a few things that have been deprecated will be obsoleted for good. Some existing function packages will be affected by these changes, so the development team is trying to act preemptively to minimise tho impact on end users. One of these packages id "sfa_mod", for stochastic frontier analysis. Since another package with comparable features is already available on the gretl server (the "frontier" package), Gordon has agreed to retire his package (thanks Gordon). If you have scripts that use Gordon's functions, feel free to contact me and I'll try to help you with the transition. ------------------------------------------------------- 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 -------------------------------------------------------
