Re: [R-sig-phylo] Determining Order of Trait Evolution

One could constrain the discrete model and then compare different ones using AICc or similar: 0 -> 1 <=> 2 vs 2->1->0 and so forth. I worry about the univariate ancestral state estimation approach because it does a reconstruction using a particular model (one where the traits are independe

Re: [R-sig-phylo] Determining Order of Trait Evolution

I've read the hOUwie paper, but it wasn't clear to me that it allowed estimating the *order* of changes. Thanks, -Rafa *--* *Rafael S. Marcondes, Ph.D.* *https://www.rafaelmarcondes.com/ * Faculty Fellow in EEB Department of BioSciences Rice University Houston T

Re: [R-sig-phylo] Determining Order of Trait Evolution

Hi Rafael, I'm interested to hear about possible better approaches than what we came up with back then. Below, I have a couple of suggestions that I would give on the way that you are doing it, though. The only slight change that I might suggest, which we have implemented in recent questions like

Re: [R-sig-phylo] Determining Order of Trait Evolution

Isn’t that what houwie does (which is fairly recently published)? https://doi.org/10.1093/evolut/qpad002 Note my conflict of interest as a coauthor. Best, Brian _ Brian O’Meara He/Him Professor, Dept. of Ecology & Evolutionary Biology University of Tenne

Re: [R-sig-phylo] Determining Order of Trait Evolution

Hi all, This is a reply to an ancient thread that I pasted below. My question is the same as the original one: how to determine the relative order of changes between a discrete and a continuous traits. I came up with the approach I describe below (inspired by Heath Blackmon in the original thread)
