You are only asking Stata to list observations where hid equals the prior
hid, so you would only see one observation (the second) from each duplicate

Subject: st: Assert question.
I have a question.
I have identifiers ranking from 1 to 9882 on 4940 observations.
I have issued a command:
and got a error message:
(6 contradictions in 4940 observations).
when I list:
list if hid[_n-1]==hid[_n]
I do not have a perfect merge so I guess the problem comes from
But I wonder why stata get confused. The values of hid are not identical.
Or am I too tired...
Thanks in advanced.
