Problem getting residuals: after merge, not all observations

Hi George,

Please try this and let us know whether this workaround solves your problem.

Yes! That works without any error messages.

Really, I should have checked and found those missing values. It's because some countries are
present in the 2010 wave, but not in 2000 or 2005.

Code: Select all

 country of |                 Wave
  interview |      2000       2005       2010 |     Total
------------+---------------------------------+----------
            | (Non-missing countries omitted) | 
          . |         0          0      5,176 |     5,176 
------------+---------------------------------+----------
      Total |    21,703     29,680     43,816 |    95,199 

Thanks again for your (speedy) help,

Ewan
