Hi to all, I 've finally started the translation of gretl into greek. It's something I have been willing to do since some years before... In other statistical software, such as Eviews, it is possible to regress a model with the Least Squares method, assuming that the residuals follow an AR(q) process. For example the resulting regression is something like y = 1.2154 + 0.2215 x + 0.251 AR(1) How is it possible to do the same in gretl? Thank you very much in advance, Constantine Tsardounis http://www.costis.name
