Dear all, I would like to ask for a little help from you. I wish to estimate the posterior probability that two ancestral nodes take particular states, given the observations of discrete trait at the tips of a tree. I was wondering if using a SCM approach described below would work.
If so, I think this can be easily done using make.simmap from phytools where I would like to assign an equal prior on the root to all states. Does the above make sense? Any insights are highly appreciated!
