fitDiversityModel {phytools} | R Documentation |
This function fits a diversity-dependent phenotypic evolution model (based on Mahler et al. 2010).
fitDiversityModel(tree, x, d=NULL, showTree=TRUE, tol=1e-6)
tree |
an object of class |
x |
a vector with tip values for a continuously distributed trait. |
d |
a vector containing the inferred historical diversity at each node in the tree - if |
showTree |
optional logical value indicating whether to plot the tree transformation implied by the model. |
tol |
some small value by which |
A list with the following components:
logL |
log-likelihood of the fitted model. |
sig0 |
estimated starting value for the rate at the root of the tree. |
psi |
the estimated rate of change in the rate associated with the addition of a lineage. |
vcv |
a matrix with the variances and covariance of the estimated parameters (from the Hessian). |
