Subject   st: How to compare Somer'D in 2 groups, clustered data

I'm working on a survey with clustered weighted data.  I want to compare Somers' D  in two groups which have members in every cluster.  With Roger Newson's -somersd-, I've computed probability-weighted estimates for each of the two groups and output the cluster-based standard errors. With these, I can compute a standard error for the difference that assumes  that the groups are independent. My problem: how to take advantage of the within-cluster comparisons.  I've already tried -suest-, but that does not work with the jackknifed standard errors produced by -somersd-.  I'd appreciate suggestions.
