st: Clustered errors with fixed effects in Stata 8

[Steve Shewfelt <steven.shewfelt@yale.edu>]

Hello,

I'm working with a cross-sectional dataset in which observations 
(households) are clustered at the village level. I have OLS and Logit 
models. I would like to use fixed effects and robust clustered standard 
errors, but the options available seem to allow for either of the two 
but not both (robust and cluster are available with regress and logit, 
but not with xtreg or xtlogit).

Also, I am doing some IV models (ivreg and ivprob). The former allows 
for robust clustered errors, but the latter doesn't.

I'm using Stata 8. Does anyone know of an ado file I can download that 
makes it possible to do what I want to do?

Thank you in advance,
