... or, if you want to do it *really correctly*, you can use the threshold
model of Sewall Wright for the discrete character and use the MCMC approach
that I proposed in 2012:
Felsenstein, J. 2012. A comparative method for both discrete and
continuous characters using the threshold model. American Naturalist 179:
145-156.
which is implemented in my program Threshml which can be called from Liam
Revell's Phytools R package. It also works for multiple threshold
characters and multiple continuous characters.
