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

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

An alternative that doesn't require discretization of the continuous trait
would be an approach I used in
http://onlinelibrary.wiley.com/doi/10./evo.12792/abstract. Briefly you
do standard ASR of both traits (continuous = ML brownian motion; discrete =
stochastic mappings) independently. Then
Hello Gavin,
You could have a look at the method for evolutionary contingency, which works
only for binary traits (meaning you’d have to transform your continuous trait
into a binary one). See Pagel and Meade 2006 (Bayesian Analysis of Correlated
Evolution of Discrete Characters by
Hi all,
I have 500 trees of 80 species downloaded from birdtree.org and am primarily
interested in two traits. I have used PGLS to determine the traits are related
but would ideally like to test if there is an order to trait evolution. To
complicate matters one trait (Trait A) is continuous
