ratematrix - Bayesian Estimation of the Evolutionary Rate Matrix
The Evolutionary Rate Matrix is a variance-covariance
matrix which describes both the rates of trait evolution and
the evolutionary correlation among multiple traits. This
package has functions to estimate these parameters using
Bayesian MCMC. It is possible to test if the pattern of
evolutionary correlations among traits has changed between
predictive regimes painted along the branches of the
phylogenetic tree. Regimes can be created a priori or estimated
as part of the MCMC under a joint estimation approach. The
package has functions to run MCMC chains, plot results,
evaluate convergence, and summarize posterior distributions.
