Resum
En este artículo se aborda la forma de construir un clasificador eficiente a través de redes bayesianas utilizadas en la minería de datos y cuya finalidad es conseguir más precisión que otros modelos empleados en los problemas de credit scoring. El enfoque bayesiano, basado en modelos de probabilidad, emplea la teoría de la decisión para el análisis del riesgo eligiendo en cada situación que se presenta la acción que maximiza la utilidad esperada. Usando una muestra de datos bancarios reales se concluye la superior capacidad predictiva de estos modelos respecto a los resultados obtenidos por otros métodos estadísticos paramétricos y no paramétricos.
