Heteroscedastic CAR models for areally referenced temporal processes for analyzing California asthma hospitalization data.


Often in regionally aggregated spatiotemporal models, a single variance parameter is used to capture variability in the spatial structure of the model, ignoring the impact that spatially-varying factors may have on the variability in the underlying process. We extend existing methodologies to allow for region-specific variance components in our analysis of… (More)
