Hello, I have 50 raters and 180 cases which are rated as malignant, probably
malignant, probably benign, and benign. I want to compare all the raters but I
want a weighted kappa to penalize differences between malignant 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!
