The extent of agreement between raters on nominally scaled data regarding a group of targets is usually computed by kappa-type indices. Recently, the homogeneity index for a qualitative variable was proposed to evaluate agreement between raters for each target, and to obtain a global measure of interrater agreement for the whole group of targets. In this presentation, some sampling properties of the proposed indices are investigated and a comparative application regarding medical data is provided.

Abstract
The extent of agreement between raters on nominally scaled data regarding a group of targets is usually computed by kappa-type indices. Recently, the homogeneity index for a qualitative variable was proposed to evaluate agreement between raters for each target, and to obtain a global measure of interrater agreement for the whole group of targets. In this presentation, some sampling properties of the proposed indices are investigated and a comparative application regarding medical data is provided.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
