<> " The reason why I have so many different datasets is that I read somewhere that Stata cannot filter observations properly, i.e. without deleting the remaining dataset." Not so, as you correctly guessed. Use the -if- qualifier! " With regard to the centile(5 50 95) command, it has only been a bit of laziness that I didn´t try to omit the 5 and 50-centiles - as soon as it worked, I was happy :-)" Omit 5 and 50, and then use - post internal (r(lb_1)) (r(c_1)) (r(ub_1))- for the -postfile- HTH Martin -----Ursprüngliche Nachricht----- Von: owner-statalist@hsphsun2.harvard.edu [mailto:owner-statalist@hsphsun2.harvard.edu] Im Auftrag von aschaich@smail.uni-koeln.de Gesendet: Mittwoch, 24. Februar 2010 01:07 An: statalist@hsphsun2.harvard.edu Betreff: RE: st: RE: AW: Re: As I told in my first post, I´m an absolute Stata rookie. The reason why I have so many different datasets is that I read somewhere that Stata cannot filter observations properly, i.e. without deleting the remaining dataset. That´s probably nonsense... So in order to deduce conditional statements, I split the original (huge) dataset into numerous sub-datasets. With regard to the centile(5 50 95) command, it has only been a bit of laziness that I didn´t try to omit the 5 and 50-centiles - as soon as it worked, I was happy :-) And by the way: Thanks a lot for the hint with the loop - I´m gonna try it right away! Here too, someone told me that looping within a filename wasn´t possible...
