Weighted kappa data considerations data a two way table that is based on an active data set is required in order to estimate the cohen s weighted kappa statistic. Cohen s weighted kappa linear scale quadratic scale asymptotic confidence interval. One of the most important features of the kappa statistic is that it is a measure of agreement which naturally controls for chance. Rating variables must be of the same type all string or all numeric.
