What worries me here is that neither in the main gretl window, nor in the show-data window, nor in the dataset info text do I see any indication of the t:i ordering. Implicitly we are supposed to remember that we declared the dataset as "stacked cross-section" back at import time. This is a recipe for confusion down the road. Instead I would suggest to convert the data to gretl's standard i:t panel internal ordering immediately on import, so the "stacked cross-section" would only apply to the import source file, not to the imported data. Perhaps that was even intended, in which case it would be a bug. Furthermore, for me the sample description line in the main window says "Undated: Full sample 1:1 - 2:4", where instead I think it should say panel data. So I'm even more inclined to think there is some bug there. In general one of my feature requests for panel data has been for a while that the current active sample should be displayed by mentioning the two different data dimensions explicity, not just with pure index numbers. But sample selection in panels is not trivial, given non-balancedness and possibly non-contiguity. thanks for the report, sven _______________________________________________ Gretl-users mailing list Gretl-users(a)lists.wfu.edu http://lists.wfu.edu/mailman/listinfo/gretl-users
