Zusammenfassung
In this work, we proposea direct spatio-temporal extension of the spatial conditional over dispersion models, where we include the spatial lag of the response variable for each time unit in thel inear predictor. The proposed models are able to capture both spatial and temporal correlations that may be present in the data under study. In addition, we also propose temporally varying spatial lag coefficient models, which allow us to study the variation in time of the spatial term. In order to illustrate their performance, we apply our proposals, for Poisson distributed responses, to the Glasgow respiratory hospital admissions dataset, where we compare their performance with the widely used Knorr-Held’ smodels.
