Hi there
Have been trying to calculate a kappa statistic for a skin lesion
colour data. The data consists of 10 raters, 22 rating categories and
100 patients.
I tried to calculate it using SAS but run into a problem because the
data has some missing values i.e raters did not assess all the lesions.
SAS requires exactly one rating for each lesion by a rater.
Looking for some feedback on how to calculate the kappa.Thanks
kind regards,
