st: cluster option in qreg

["Norma Coe" <nbcoe@nber.org>]

I am running median regressions w/ 'qreg'.  The problem is that I also want 
to correct the standard errors for potential correlation between 
observations within each state -- like the cluster() option does 
in 'regress'.  Does anyone know how to do this?

Thanks in advance,
Norma
