Hello everyone,
I am doing a regression using the following command: oaxaca gaseu l_exp age sq_age ed_dummy* bigregion_dumm* density_dummy*, by (gender) relax pooled. Where the following result is obtained.
My question is: How do I interpret, both for the explained and unexplained part the coef of the dummy variables? Why in the explained part there is always a reference variable but in the unexplained part there is not? Why only for the dummy variable bigregion_dummy* there is a reference variable both in the explained and unexplained part?
