Hi all, I'm working on the phylogenetic signal tests for continuous traits using K statistics and Pagel's lambda implemented in phytools. I'd like to know whether normal distribution of the trait values must be tested before phylogenetic signals are tested, and if the trait data are not normal distributing, do I have to transform the data? I have looked for this issue in my paper collections as well as on the internet, but still have no idea. It would be very nice if someone can give me some advice, or any paper/reference/website would also be very helpful. Thanks a lot!
