Hi Diego,
If your tree has polytomies and the branches have no length information, I am
not sure if likelihood model-based reconstruction is right.
The ace function (and all other similar functions based on likelihood) will
assume that your branch lengths represent some kind biological
Dear colleagues,
I am trying to estimate ancestral states for two binary characters in a
full morphology-based phylogenetic tree. I am using ace function,
type="discrete" and kappa=0 as arguments. Unfortunately, I am dealing with
two problems about this issue: my topology have three polytomies
