Dear Clint, I didn't catch it! For example, I want to know what is the first observation (now by which index) more than mean in a column? I want its index number. thanks ----- Original Message ----- From: Clinton Thompson <clintonjthompson@gmail.com> To: statalist@hsphsun2.harvard.edu Cc: Sent: Sunday, 10 March 2013, 13:05 Subject: Re: st: index number of an observation You can create the index first w/ a system variable, like this: gen index = _n The variable, index, should then uniquely identify each observation in your dataset and can then be used to reference a specific observation. Type -findit subscripting- (without the dashes) for more information.
