Evaluation of spatial Bayesian Empirical Likelihood models in analysis of small area data
Dr Farzana Jahan, Murdoch University.
Bayesian empirical likelihood (BEL) models are becoming increasingly popular as an attractive alternative to fully parametric models. However, they have only recently been applied to spatial data analysis for small area estimation. This study considers the development of spatial BEL models using two popular conditional autoregressive (CAR) priors, namely BYM and Leroux priors. The performance of the proposed models is compared with their parametric counterparts and with existing spatial BEL models using independent Gaussian priors and generalised Moran basis priors. The models are applied to two benchmark spatial datasets, simulation study and COVID-19 data. The results indicate promising opportunities for these models to capture new insights into spatial data. Specifically, the spatial BEL models outperform the parametric spatial models when the underlying distributional assumptions of data appear to be violated.
About the Speaker
I am a passionate about statistics and data science teaching and research. I have over 3 years experience in university teaching in Australia and experience of over 3 years in Bangladesh. I recently completed my PhD from Queensland University of Technology, Queensland, Australia. My PhD research was about Bayesian spatial modelling for small area level data. My research interests include: Bayesian Statistics, spatial modelling, modelling aggregated level data. The area of application includes but not limited to health and environment. I wish to balance between teaching and research and contribute to Statistics and Data Science discipline by getting involved in collaborative projects.
Refreshments and Dinner
