Statistical Analysis and Research Conducted by the Centre for Applied Statistics (CAS), UWA 2019This project represents collaborations between CAS and other parties, generally involving the development of improved statistical techniques for the analysis of large and complex data. The primary project that utilised the allocation in 2019 was: Fully Bayesian Spatio-Temporal Modelling of Daily Precipitation.

Model site-specific daily rainfall measurements at many locations across Australia.
Site-specific daily rainfall measurements at many locations across Australia were modelled, with the models focusing on capturing all features of daily rainfall measurements: temporal variation, missing rainfall measurements, zero-rainfall days, and extreme tail behaviour. The project code was mainly written in C++, with some pre-processing in R.
The project involved computing several variants of a model across the different locations. Use of the Pawsey facilities was required in order to estimate these models, due to a high computational burden arising from their complexity.
