Query: A Bayesian localised conditional auto-regressive model for estimating
  the health effects of air pollution   Estimation of the long-term health effects of air pollution is a challenging
task, especially when modelling small-area disease incidence data in an
ecological study design. The challenge comes from the unobserved underlying
spatial correlation structure in these data, which is accounted for using
random effects modelled by a globally smooth conditional autoregressive model.
These smooth random effects confound the effects of air pollution, which are
also globally smooth. To avoid this collinearity a Bayesian localised
conditional autoregressive model is developed for the random effects. This
localised model is flexible spatially, in the sense that it is not only able to
model step changes in the random effects surface, but also is able to capture
areas of spatial smoothness in the study region. This methodological
development allows us to improve the estimation performance of the covariate
effects, compared to using traditional conditional auto-regressive models.
These results are established using a simulation study, and are then
illustrated with our motivating study on air pollution and respiratory ill
health in Greater Glasgow, Scotland in 2010. The model shows substantial health
effects of particulate matter air pollution and income deprivation, whose
effects have been consistently attenuated by the currently available globally
smooth models.
