<>That is the thing about posts with example data in them. You cananswer the request based on the structure of the data that you observein the post. That means you assume that the poster knows best and gavean accurate representative sample of his data.Or you think ahead and anticipate that there must be some kind ofproblem in there that the poster does not regard as a problem, e.g.missing values. But you run into a new problem then: We do not knowwhat John wants to happen if there are missing values. Maybe he stillwants the -egen, count()- solution even then?I chose the former attitude to the problem, but I recommend that Johnpay close attention to Nick`s recommendation and implement them if hefeels they do what he wants...HTH Martin _______________________ ----- Original Message ----- From: "Nick Cox" <n.j.cox@durham.ac.uk> To: <statalist@hsphsun2.harvard.edu> Sent: Sunday, March 29, 2009 6:02 PM Subject: st: RE: Re: Fill in panel observationsThere will be a difference between the results bys iis: egen total_rater = count(rater) and bys iis : gen total_rater = _N if -rater- is ever missing; but otherwise the latter is more direct and more efficient. Incidentally, once you known that data are sorted on -iis-, the second command can just start -by iis:-. Nick n.j.cox@durham.ac.uk Martin Weiss bys iis: g rater=_n bys iis: egen total_rater=count(rater) John AntonakisI have multiple observations on leaders (iis) by raters, like this: iis sex age y rater total_rater 1 0 43 5 1 5 1 0 43 9 2 5 1 0 43 3 3 5 1 0 43 6 4 5 1 0 43 6 5 5 2 1 46 9 1 7 2 1 46 7 2 7 2 1 46 9 3 7 2 1 46 6 4 7 2 1 46 7 5 7 2 1 46 2 6 7 2 1 46 8 7 7 At this time, the rater column and total_rater columns are blank. I would like to fill them in such that: a. Under "Rater" I number each within the panel, starting with 1 and going up to k raters (as I have done above). b. The total number of k raters is included for each leader (as in thetotal_rater column). Is there a quick way to do this?* * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/* * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
