Hi all,

 I am a PhD Research Scholar from IGIDR, Mumbai, India. I am facing a
problem using the heteroscedasticity test (hettest) after the areg
command in STATA. below is what I do in my do file.

#delimit;
areg lnexp lhsize meanage sexratio maleratio adultratio meanedu
maxedu, absorb(cluster);
hettest;

This is giving me the error as follows.

last estimates not found
r(301);

The same hettest command is working well when I am using the
simple "reg" command. But I have to use areg so that it creates
cluster dummies automatically and use them in the regression.

I would be happy if any one could help me with this..

Regards,
Rijo John.
