Dear Ms. Llopis, It is my understanding that you are correct, Brownian evolution is a generally considered an assumption in PIC (see Felsenstein, J. 1985. Phylogenies and the comparative method. American Naturalist 125: 1-15). Its inclusion is important to Felsenstein's formulation because it allows the procedure to yield statistically independent variables, which is an assumption in nearly all statistical analyses.
Hope this helps, James Soda On Sat, Feb 20, 2016 at 8:57 AM, Cristina Llopis < cristina.llopis.beleng...@gmail.com> wrote: > Dear all, > > I'm studying evolutionary modularity. > I'm performing a PIC analysis on MorphoJ.
