Abstract

In this article, we describe tabagree, a new command for assessing the level of agreement and disagreement in paired ordinal data. tabagree implements some of the nonparametric measures proposed by Svensson (1993, Analysis of Systematic and Random Differences Between Paired Ordinal Categorical Data [Almqvist and Wiksell]) and allows the user to evaluate systematic disagreement separately from random differences. For example, the command can be used in interrater and intrarater reliability studies or in analyses of change.
