Abstract: A hierarchical spatio temporal regression model is introduced to study the spatial and temporal association existing between health data and air pollution. The model is developed for handling measurements belonging to the exponential family of distributions and allows the spatial and temporal components to be modelled conditionally independently via random variables for the (canonical) transformation of the measurements mean function. Pollution exposure are linked with the health outcomes through a regression model which allows for time variation in parameters (e.g. Markov switching, structural break models, threshold models, etc.).
