Hi to all "cointegration junkies" (as Jack calls them), I have just uploaded new versions (0.9.3) of the three py4gretl function packages, fixing some problems related to temp files and communication between gretl and python. The functionality is the same; results should also mostly remain the same in those cases where the old versions didn't fail. However, if you specified unrestricted exogenous variables along with no restricted exogenous variables, you got wrong results! Because this was due to a bug in gretl, (and because of some other internal changes), the required gretl version for py4gretl is now set to >=1.6.3. I'm happy about any feedback you might have. cheers, sven
