La comparación de dos proporciones independientes p1 y p2 a través de las medidas diferencia, razón y odds ratio, es muy frecuente en diversos ámbitos. Las inferencias sobre estos parámetros suelen utilizar estadísticos asintóticos basados en el estadístico de las marcas (S), que no corrigen el sesgo del estimador del producto pi(1-pi). Por ello Miettinen y Nurminen propusieron los estadísticos MN consistentes en multiplicar los estadísticos S por (N-1)/N, con N el tamaño total de muestra. En este trabajo se demuestra que el factor (N-1)/N es el correcto solo para el test de homogeneidad, proporcionándose la estimación del factor correcto (estadísticos AU) y del valor mínimo del mismo (estadísticos AUM). Además se evalúa el comportamiento de los cuatro estadísticos aludidos en los test de 1/2 colas para cada uno de los tres parámetros citados. La conclusión es que los mejores estadísticos son los de tipo AUM, seguidos a gran distancia por los de tipo MN (similares a los de tipo AU).

Keywords: diferencia de proporciones, estadístico de las marcas, estudios prospectivos, estudios retrospectivos, estudios transversales, odds ratio, riesgo relativo
