Dear Statalisters,
I'm using the heckman procedure with survey data. I have an
interaction term (yearsstudy_placelive) that is a product of a
continuous variable and a dummy variable. My model is
*****************
svy linearized: heckman lnincome age age2 years_study place_live
yearsstudy_placelive, select (ocup = age age age2 years_study
place_live yearsstudy_placelive race region) log
****************
where place_live is a dummy (0=rural; 1=urban)
I�m using margeff, because it�s easy to calculate the total effect of
age. However, I actually don�t known how to calculate the effect of
the interaction term in the regression model. I only can use inteff
after probit or logit.
Then, I really appreciate an advice of how I can calculate this effect.
Thanks a lot,
Joao Lima
