In the presence of many zero counts, however, this prior may not be satisfactory either. A model selection approach is proposed, allowing for the possibility of zero parameters corresponding to zero count categories. This approach results in a posterior mixture of Dirichlet distributions and marginal mixtures of beta distributions, which seem to avoid the problems that potentially result from the various proposed Dirichlet priors, in particular in the context of extreme data with zero counts.]]> Thu 06 Oct 2022 15:06:32 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:11194 Sat 24 Mar 2018 08:13:36 AEDT ]]>
