[Gretl-users] Series and lists as bundle members

Dear all, in my opinion a brief description in the manual of how series, bundles and restrictions work might be helpful. As example: <hansl> nulldata 10 s = index % 2 ? NA : 1 bundle b = null smpl 1 5 b.s1 = s smpl full smpl --no-missing b.s2 = s smpl full print b </hansl> <output> bundle b:   s1 (series: length 10)   s2 (series: length 5) </output> I suppose that the series "s1" has 10 element for "preserving information", because in "smpl 1 5" you could use only a part of "s", but you cannot do that with "--no-missing" because the series after sampling is completely different. Anyway, it isn't obvious at first sight why series s1 and s2 have different length. What do you think? Regards Federico Fiorani
