Resumen

La importancia del análisis cuantitativo del deporte a través del uso de estadísticas de juego ha sido un área de creciente interés en los últimos años. En esta investigación mostramos una aplicación de la estadística espacial al entendimiento del juego en baloncesto. Esta metodología ha sido infrautilizada en la investigación en deporte hasta la fecha, especialmente en baloncesto. Así, describimos una técnica de segmentación espacial, como el test de Kulldroff, que es ampliamente utilizado en epidemiología, y puede ser aplicado para analizar estadísticas de juego en baloncesto. Este test detecta clusters de lanzamientos de baja y alta incidencia, caracterizando mejor el juego de los equipos y de los jugadores. Además, desarrollamos un test basado en entropía, el test V, que permite comparar los mapas de lanzamiento. Para ilustrar empíricamente el atractivo de esta aproximación metodológica, aplicamos estos análisis al rendimiento del equipo de la NBA: Los Angeles Lakers. Este equipo vivió una enorme transformación en las últimas temporadas, pasando de ser una franquicia de rendimiento medio a ganar la NBA, debido a, entre otros factores, la incorporación de dos jugadores clave en la temporada 2007-08: Pau Gasol y Derek Fisher.
