Hi there,
I'm having a problem with grqreg, a stata module to graph confidence
intervals for quantiles.
I have the Dec. 2006 version of grqreg.
I am using the card dataset from http://www.stata.com/texts/eacsap/
The following works:
qreg lwage educ
grqreg, ci olsci
But if I add regressors, it fails:
qreg lwage educ exper expersq black south smsa smsa66 reg661-reg668
grqreg, ci olsci
The error message is "labels.Arrpush invalid name"
Any ideas where the problem might come from is warmly welcome!
Patrick.
