Dear all:
I am applying the pgls function in caper to test for the relationship
between a dependent and an independent variable. Usually, the
regressions can be well interpreted when applying the lambda branch
lenghth transformation. However, in one case, the regression became

Hope this helps

Another issue is that the tree is not ultrametric. If you use nlme::gls
to fit the mode
to REML.
Also, “gls” estimates a correlation rather than a covariance structure. On
non-ultrametric trees (such as yours) this will lead to different results.

Dear list members:
I tried various R packages to calcuate a PGLS with the data set (csv
and nwk) I have attached to this email. I would like to use the Pagels
lambda model to attain an index that measures whether data exhibit
phylogenetic dependence or not.
While doing so, I came up wit
