Research

My research mainly considers aspects of Distribution Theory and Directional Statistics. The book and various of the papers identified below deal with Circular Statistics, a branch of the wider field of Directional Statistics. The focus of much of my recent research has been the identification of tractable and flexible models capable of describing those features (such as varying degrees of asymmetry and kurtosis) often exhibited by real data as well as the development of methods of statistical inference for them.
