Cohen's kappa statistic is the conventional method that is used widely in measuring agreement between two responses when they are categorical. In this article, we develop a fixed-effects modeling of Cohen's kappa for bivariate multinomial data which reduces to Cohen's kappa under certain conditions and hence can be considered as a generalization of the conventional Cohen's kappa. Also, this method can easily be adapted as a generalization of Cohen's weighted kappa. Properties of the proposed method are provided. Large sample performance is investigated through bootstrap simulation studies followed by two illustrative examples.
