regression is leaving out one observation in the data set: how to tell which?

[Sid Molloy]

Hi:

I have a data set containing 195 observations. When I run a regression (meqrlogit) it tells me the "number of obs = 194".

I'm wondering if there's a command that will tell me which observation is being left out.

Any help would be much appreciated.

Cheers

sysuse auto
reg price mpg rep78 if foreign==1
gen flag=1 if e(sample)==1

with that last line flagging each observation included in the last rgeression

 gen flag = e(sample)

is even better.
