Title: Comparing Dependent Association Measures for Categorical Data
Author(s): Klaus Kähler Holst*+ and Esben Budtz-Jørgensen
Companies: University of Copenhagen and University of Copenhagen
Keywords: categorical data ; interrater agreement ; asymptotics ; concordance ; ordinal data
Abstract:

We consider the problem of comparing possibly dependent association measures between two categorical variables. By considering the influence functions of the association measures we will show how different test-statistics and their limiting distributions can be obtained. Extensions to a regression framework will be discussed and the method will be illustrated on both real data and the performance examined in simulations.
