Abstract: kappa2 is a generalization of the kappa coefficient to allow using weights and an explicit agreement definition for multiple raters and incomplete designs. Computations are done using formulae proposed by Abraira V. In the particular case of unweighted kappa, kappa2 would reduce to the standard kappa Stata command, although slight differences could appear because the standard kappa Stata command uses approximated formulae (see [R] kappa). kappa2 calculates the kappa-statistic measure of interrater agreement when there are two ore more unique raters and two or more ratings. It assumes that each observation is a subject. varname1 contains the ratings by the first rater, varname2 by the second rater, and so on. To facilitate the use of this command, its syntax is an extension of the standard kappa command, and hence kappa2 has the same options than kappa but it includes some new ones. This help document copies the standard kappa help and introduces the novelties.
