Hi Joe, Yes, I meant forward and backward rates are different at a single site. I mistakenly thought that different forward and backward rates make the model nonreversible. Thanks for the correction. -Jordan > On Sep 19, 2018, at 12:21 AM, Joe Felsenstein wrote: > > Jordan Gault asked: >

Hello all, I’m putting together a short lecture on ancestral state reconstruction and would like to include some worked examples of marginal ancestral state reconstruction on a small phylogeny. I’ve managed to do the calculations by hand for a binary, discrete character under an equal-rate
