    2 Raters
    The agree option, on the proc freq tables statement, will calculate kappa statistics between 2 raters.
    More than 2 Raters
    The %MAGREE macro, from the SAS website computes estimates and tests of agreement among multiple raters when responses (ratings) are on a nominal or ordinal scale. For a nominal or ordinal response, kappa statistics can be computed. For a numerically-coded, ordinal response, Kendall's coefficient of concordance is computed. Kappa with Multiple Raters
