Hi All:
Could anyone point me to a package that can calculate stratified kappa?  My
design is like this, 4 raters,  30 types of diagnosis scores, 20 patients.
Each rater will rate each patient for each type of diagnosis score. The
rater's value is nominal.

I know I can measure the agreement between raters for each type of diagnosis
score, e.g., calculate out 30 kappa values. My problem is I want to have an
overall agreement measure (a single value and its significance over chance).
Could anyone help me with this?

Thanks in advance,

FD
