| Subject | st: How to compare Somer'D in 2 groups, clustered data |
| Date | Sun, 20 Mar 2011 21:19:53 -0400 |
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.
