Hello,

I am using the kappa command to evaluate the reliability of survey questions, and have installed the kapci program to compute confidence intervals for kappa values. Some of the survey questions seem to have moderate to high levels of % agreement but have low kappa values. In addition, some of the confidence intervals that are generated using the kapci command do not have lower bounds. Are there any suggestions?

I am computing unweighted and weighted kappa statistics and confidence intervals. Here is sample code (for comparing participant responses to the same survey question asked at two different times-this was an ordered categorical question):

kap q_1717 q_1801, tab
kapci q_1717 q_1801, reps(1000)
kapci q_1717 q_1801, w(w2) reps(1000)

Thanks,
Jen
