Likelihood for joint λ
Computes the joint likelihood of Pagel's λ parameter.
likMlambda(lambda, X, C)
lambda |
scalar, usually on the interval 0,1 (although not required to be). |
X |
data for various continuous character, in the form of a matrix. |
C |
n x n matrix (for n taxa) containing the height above the root for each pair of taxa in the tree (e.g., |
Generally intended to be used internally by other methods that do joint optimization of λ (e.g., phyl.pca).
