Hi Nick, I will def. need the tab command later. Thanks. What I meant was like this: In the example below, 3 countries are covered by the variable x1. When I run a regression (xtreg) with x1, that will give me the number for countrynumber. But I was wondering if there's a command like 'tab' which will give me the count. countryno x1 1 0.55 1 0.55 1 0.55 0.55 . 0.55 . 0.55 2 0.55 2 0.55 2 0.55 2 0.55 . 3.31 . 3.87 . 4.42 . 4.97 . 5.52 6.08 . 6.63 3 7.18 3 7.73 3 8.29 On 24 May 2011 11:49, Nick Cox <njcoxstata@gmail.com> wrote: > I am not clear what "covered by" means in Stata terms. > > . tab country > > lets you count distinct countries, which are returned in r(r). > > Also see > > SJ-8-4 dm0042 . . . . . . . . . . . .
