Hi everybody, just a quick notice that recently two new contributed function packages have seen the light of the gretl world: - 'ARprobit', which implements the Kauppi&Saikkonen approach to estimate a dynamic Probit model including an autoregressive term (in addition to lags of the dependent dummy). - 'hamilcycle', which applies the simple but already popular proposal by Hamilton to do a regression-based filter of a time series to obtain a cyclical component (based on an idea by Jack a year ago) As always (sorry for being repetitive) you can get these and other contributed packages online from within gretl ("fx" button at the bottom, or through the menu File/Function packages/On server). cheers sven
