Hello,
I am bumping up this question from 2004, as it addressed my issue.
I want to correct the standard errors for potential correlation between observations.
Is there a cluster() option equivalent? It appears that there is not, according to the Stata help files.
Will bootstrap (reps(#)) provide me with the results I am looking for?
Also, is there a command to identify the intraclass correlation coefficient, to determine if there is indeed clustering? Or will it be okay if I bootstrap anyway, regardless?
Also, what is a typical rep number, 1000? Or will 100 suffice?
Thank you

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
