Mixture models for spherical data with applications to protein bioinformatics
Kanti V. Mardia, Stuart Barber, Philippa M. Burdett +2
Finite mixture models are fitted to spherical data. Kent distributions are used for the components of the mixture because they allow considerable flexibility. Previous work on such…
Families of discrete circular distributions with some novel applications
Kanti V. Mardia, Karthik Sriram
Motivated by some cutting edge circular data such as from Smart Home technologies and roulette spins from online and casino, we construct some new rich classes of discrete distribu…
Score matching estimators for directional distributions
Kanti V Mardia, John T Kent, Arnab K Laha
One of the major problems for maximum likelihood estimation in the well-established directional models is that the normalising constants can be difficult to evaluate. A new general…
A new method to simulate the Bingham and related distributions in directional data analysis with applications
John T. Kent, Asaad M. Ganeiber, Kanti V. Mardia
A new acceptance-rejection method is proposed and investigated for the Bingham distribution on the sphere using the angular central Gaussian distribution as an envelope. It is show…
Some Fundamental Properties of a Multivariate von Mises Distribution
Kanti V. Mardia, Jochen Voss
In application areas like bioinformatics multivariate distributions on angles are encountered which show significant clustering. One approach to statistical modelling of such situa…
Directions and projective shapes
Kanti V. Mardia, Vic Patrangenaru
This paper deals with projective shape analysis, which is a study of finite configurations of points modulo projective transformations. The topic has various applications in machin…
