The identifiability of tree topology for phylogenetic models, including covarion and mixture models.

摘要: For a model of molecular evolution to be useful for phylogenetic inference, the topology evolutionary trees must identifiable. That is, from joint distribution predicts, it possible recover tree parameter. We establish identifiability number models, including covarion and variety mixture models with limited classes. The proof is based on introduction more general model, allowing states at internal nodes than leaves, study algebraic formed by distributions which gives rise. Tree first established this through use certain invariants.
