In recent years, spatial and spatio-temporal modeling have become an
important area of research in many fields (epidemiology, environmental studies,
disease mapping). In this work we propose different spatial models to study
hospital recruitment, including some potentially explicative variables.
Interest is on the distribution per geographical unit of the ratio between the
number of patients living in this geographical unit and the population in the
same unit. Models considered are within the framework of Bayesian Latent
Gaussian models.
