Hi Everyone,
I am trying to use Oaxaca by Ben Jann of May 08 with the categorical
option and I dont know why I get the error:
"categorical(): no reference indicator found".
The command I am running is the following:
.oaxaca ln_hwage educa age exper expersq condnum1-condnum8 formal
urban uf1-uf27 sector1-sector12 if female==0, by(white) noisily
weight(0) eform svy categorical(uf? uf??, condnum?, sector? sector??).
Does anyone know why?
Thanks a lot,
Luana
