Hi Sereina.
Why lambda=0.5? Normally investigators tend to compare a model where
lambda is estimated to one in which it is fixed at 1 which corresponds
to Brownian evolution; or 0 which corresponds to no phylogenetic
correlation in the residual error of the model.
We can compare two fitted m
Dear all,
I have a question conserning the pgls regression in package caper. The function allows to estimate or fix three branch length transformations. I wanna figure out which transformation gives me the best model fit by comparing for example a model with lambda estimated (lambda="ML") to a
