    Este trabajo introduce el uso de grafos en el análisis de los determinantes del gasto de los turistas y lo aplica al estudio del comportamiento de los pasajeros de cruceros que desembarcan en Uruguay en los puertos de Montevideo y Punta del Este. Este enfoque ofrece un abordaje alternativo a los usualmente empleados para analizar los determinantes del gasto turístico al introducir una representación gráfica que permite sintetizar y visualizar las relaciones entre el conjunto de variables que caracterizan a los turistas o grupos de turistas y los determinantes de su nivel de gasto. En particular, la metodología permite representar las relaciones de dependencia entre variables (entre nodos adyacentes) e independencias condicionadas (entre nodos no adyacentes). Para su aplicación, se consideran datos individuales de las encuestas realizadas a cruceristas correspondientes a la temporada de cruceros comprendida entre noviembre de 2014 y abril de 2015, ambos incluidos, en Uruguay. Se estudia la existencia de dependencias de las variables relativas a registrar el gasto de los cruceristas con otras variables (sociodemográficas, de contexto, etc.). El estudio muestra que las variables que mejor explican el comportamiento de los visitantes son las vinculadas al puerto de desembarco y al gasto. Asimismo, los resultados muestran que las variables socioeconómicas no están vinculadas al gasto en forma directa

    This paper introduces the use of graphs in the analysis of the determinants of tourists' expenditure, providing an alternative approach to the methods usually employed. Graph-based analysis is applied to study the behavior of cruise passengers arriving at the ports of Montevideo and Punta del Este in Uruguay. The graphical representation allows to synthesize and visualize the relationships between the set of variables that characterize tourists or tourist groups and the determinants of their level of spending. The graph-based methodology is particularly suitable to represent the dependency relationships among variables (between adjacent nodes) and conditional independence (between non-adjacent nodes). For the empirical application, individual data from the surveys of cruise passengers corresponding to the cruise season between November 2014 and April 2015 in Uruguay are considered. The existence of dependencies between spending variables and other variables that may be of interest (sociodemographic, contextual, etc.) is studied. The exercise shows that the variables that better explain visitors' behavior are linked to the port of disembarkation and the expenditure. The results also show that socioeconomic variables are not directly linked to spending.
