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

...ignant and benign more than differences between malignant and probably malignant. I only found the weighted option in the 2-rater functions (kappa2, wkappa, cohen.kappa). The functions I found for multiple raters do not include a weighted option for categorical data (kappam.fleiss, kappam.light, lkappa). Anyone know a function that allows the calculation of weighted kappa for m raters? Thanks in advance! ~Marwa [[alternative HTML version deleted]]
