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.
The options are
bootstrap k=r(kappa) , cluster(clinic) rep(1000) : kap a b
bootstrap k=r(kappa) , strata(clinic) rep(1000) : kap a b
Kind regards, Garry
