Hi,

This is my model:

Code:
logit smoker lninc
Where lninc, is the log transformation of the income variable. I want to find the income elasticity of smoking participation.
Is the following code sufficient to calculate this value:

Code:
margins, eyex(lninc)
Or is it more appropriate to use:

Code:
margins, eydx(lninc)
Seeing as the income variable has already been log transformed.

Would the correct interpretation of this elasticity be the "average income elasticity of smoking participation"?

Thank you for any help, anyone can provide.
