Is there a reason why -margins- and -lincom- produce different confidence intervals?  Perhaps the question should be: what is the difference between estimation by -margins- and -lincom-.  The difference is pronounced at smaller sample sizes.  For example:

webuse margex
sample 1     // draw a 1% sample of the data
regress y
margins sex

The interesting thing is that the estimates appear to be identical, except for the confidence intervals.

Any insights would be welcome!
