Re: [R-sig-phylo] ancestral estimation under OU model

Hi Oscar. You can fit the OU model using (for example) fitContinuous in the geiger package, transform your tree using the fitted value of alpha, and then estimate ancestral states using BM. This will give you the same ancestral states as if you simultaneously fit the OU model to the tree.
