Objectives To estimate the annual burden of mortality and the associated health costs attributable to air pollution from wood heaters in Armidale. Design Health impact assessment (excess annual mortality and financial costs) based upon atmospheric PM2.5 measurements. Setting Armidale, a regional Australian city (population, 24 504) with high leve...

Ambient fine particulate matter <2.5 µm (PM2.5) air pollution increases premature mortality globally. Some PM2.5 is natural, but anthropogenic PM2.5 is comparatively avoidable. We determined the impact of long-term exposures to the anthropogenic PM component on mortality in Australia. PM2.5-attributable deaths were calculated for all Australian Sta...

Exposure to traffic related nitrogen dioxide (NO2) air pollution is associated with adverse health outcomes. Average pollutant concentrations for fixed monitoring sites are often used to estimate exposures for health studies, however these can be imprecise due to difficulty and cost of spatial modeling at the resolution of neighborhoods (e.g. a sca...

Massive datasets are increasingly encountered in modern research applications, and this presents tremendous new challenges for statisticians. In settings where the aim is to classify or cluster data via finite mixture modelling, such as in satellite image analysis, the large number data points to be analysed can make fitting such models either infe...
