But we really need some more gretlers who are in a position to make the gretl wish list _shrink_! (That is, by implementing some of the items on the list.) Jack and I are currently working on more advanced cointegration methods (and we added the Heckit estimator a few days ago). We also have on our agenda such things as more general GARCH methods, structural VARs, simulation of simultaneous equation systems, and making the Kalman filter (currently used in the background for ARMA estimation) accessible at the user level. Plus duration models, Blundell-Bond panel estimation, ... If you know of any graduate students with programming expertise who might be interested in contributing to gretl, please try to encourage them to do so! Allin.
