Extensions of the Dixon and Coles model

Extensions of the Dixon and Coles model

In 1997 Dixon and Coles proposed a model for football by extending the Double Poisson model. The model added some kind of dependence to the known Double Poisson model but also allowed to transfer some probability to particular scores. The range of correlation provided by the model is limited but sufficient for some championships. Since then the model has found wide applicability. In this talk I will present my work with colleagues that extend the idea of the model in different directions. The key idea is that the Dixon and Coles model can be seen as a special cases of some known family of distributions and hence its extension can be put simply into this framework. I will also present extensions to several directions as well as few applications of the new extended model.  Properties of the extended model will be also discussed to better understand the new model.

The talk was given by Dimitris Karlis from the Athens University of Economics and Business.
