Abstract

En este trabajo se discuten diversos modelos de regresión para el análisis de datos de recuento de corte transversal,haciendo especial hincapié en la forma en que cada uno recoge dos de las características más comunes de este tipo de datos, el exceso de ceros y la heterogeneidad no observada. Además se lleva a cabo su aplicación en un conjunto de datos sobre patentes, concedidas por la Oficina Europea de Patentes (OEP). En concreto se analiza una de las relaciones propuestas en la literatura, la planteada entre el número de citas recibidas por las patentes y el alcance de las mismas, considerando, además, otro conjunto de características que pueden ser relevantes en la explicación del número de citas. La comparación de los resultados obtenidos con las distintas aproximaciones ilustra la influencia del tipo de modelo elegido sobre las conclusiones que pueden extraerse.
