Is there a way to get a confidence interval in this situation?
for example
gen dummy = 1
reg depvar age sex
adjust if e(sample), by(dummy) gen(var1)
adjust iage = 40 sex = .5 if e(sample), by(dummy) gen(var2)
gen diff = var1 - var2
Is there a way to get a confidence interval for this difference? I assume
that just ci diff is not appropriate.
Thanks,
Fred
