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 while the second (Trait B) is presence/absence. I was hoping someone could direct me to methods (assuming they exist) that would allow me to determine the estimated value of Trait A before a gain of Trait B evolves in a lineage.
