It’s great to be able to use my research experience in estimating overdispersion on an important scientific problem. One of the key aspects of the problem is the sparseness in the data, which are multinomial with a very large number of categories.
Joint work with Farzana Afroz and Matt Parry will be particularly useful in this setting, as we were able to derive an estimate of overdispersion that works really well for sparse multinomial data: the paper we published can be found here.
I am delighted to be working with James Reardon from the NZ Department of Conservation on a project concerned with sustainable mouse control. It will be good to get into the design and statistical modelling issues in this study.
