Dear Reduced Forum,
This is a question for Stata Corp, not for us. Tom
************************************************************ *****
I'll try following up with Stata re:
Do you know what Stata does regarding estimating cluster-robust standard errors using the svy: command? If it is using the "cluster robust" sandwich estimator, clustering at PSU and Household would be the same as clustering at PSU. But if its using some random-effects-type correction (some Moulton-type paramteric specification of the V/C matrix of error terms), then multi-level clustering would be different. I've never figured out what Stata is doing with the svy. Using "reg Y X, cluster(clustervar)" uses the sandwich estimator that would subsume household in PSU, but it sounds like that is not what svy: is doing.
