Exponentiate results from margins

[Anna Stubbendorff]

Hi!

I want to run a regression on the log-scale and exponentiate the results. How do i do that?

Example:
regress Blood_log BMI i.city
margins i.city, expression(???)

Maybe like the following.

sysuse auto

generate double ln_mpg = ln(mpg)
regress ln_mpg c.weight i.foreign
margins foreign, expression(exp(predict(xb)))

// Consider also
glm mpg c.weight i.foreign, family(gaussian) link(log) nolog
margins foreign

// Or even
poisson mpg c.weight i.foreign, vce(robust) nolog
margins foreign
