Nick,

Referring to the code you posted below:

Is it possible to twitch it somehow so that it, for each unique person as 
defined by the person id variable, keeps only the observation form the last 
panel. In other words, I want to create a cross-sectional dataset in which 
the observations (one per person) may stem from different panels.

Best regards,

Christer Thrane



The code:

program balance, sort
    version 8.2
    syntax [if] [in]
   marksample touse
    tempvar count
    qui {
       local ivar: char _dta[iis]
   if "`ivar'" == "" {
di as err "no identifier set"
exit 498
   }
       bysort `touse' `ivar': gen long `count' = _N
        sum `count' if `touse', meanonly
       keep if `count' == r(max) & `touse'
    }
end
