Resumen de Generalization of the Kappa coeficient for ordinal categorical data, multiple observers and incomplete designs

Víctor Abraira , Alberto Pérez de Vargas Luque

• This paper presents a generalization of the kappa coefficient for multiple observers and incomplete designs. This generalization involves ordinal categorical data and includes weights which permit pondering the severity of disagreement. A generalization for incomplete designs of the kappa coefficient based on explicit definitions of agreement is also proposed. Both generalizations are illustrated with data from a medical diagnosis pilot study.
