After a review of some of the implications for statistical modelling and analysis of probabilistic results about the Dirichet Process and its close relatives, we introduce a class of simple mixture models in which clusters are of different ‘colours’, with statistical characteristics that are constant within colours, but different between colours. Thus cluster identities are exchangeable only within colours. The basic form of our model is a variant on the familiar Dirichlet process, and we find… CONTINUE READING
