Dear all,

I am using oaxaca to compare two groups in survey data. I include industrie dummies. Because one group is very small, I run into troubles because a considerable part of the industrie categories is not filled by the small group. Consequently, by default, oaxaca stops and returns an error. I get the command running by using the option relax. But how does it work? I am mainly concerned about interpretation. If I can not get the coefficients in one model, how should I be able to calculate any difference with the other group? Am I limited to the interpretations for the population for which I have a common support for the industries between the two groups? Any help would be appreciated.

Best

Daniel
