Hi, I ran a simple OLS and invoked the margins, eyex(*) to calculate
the elasticities.  I try to replicate the elasticity estimates by
running the sample regression with logged dependent variable, and
independent variables.  I was surprised that the coefficient estimates
from the logged regression are not identical with the margins
estimates.  Initially, I thought the discrepancies are due to atmeans
and asobserved options with margins.  But I tried both options and
still cannot replicate elasticity estimates by the logged regression.
Could someone explain?
Thanks,
Albert.
