Abstract

Phylogenetic data arising on different tree topologies might be mixed on a given alignment. Models taking into it account usually contain a large number of parameters and the usual tests for model fitting cannot deal with them. Here we discuss an approach for model fitting of algebraic models on m-tree mixtures. This is joint work in progress with Marta Casanellas and Jesus Fernandez-Sanchez
