Dear Statalist,

I am calculating kappa over six clusters, which range in sample size from 30 to 150.
I wish to adjust the 95% confidence intervals for possible lack of independence of observations.
The clusters could be patients within medical clinics.

I was enquiring which of either the cluster option or the strata option of the bootstrap command would be appropriate.
You might consider using -kapci- written by Michael E. Reichenheim and downloadable from ssc.

P Before printing, think about the environment
