Re: [R-sig-phylo] phylogenetic circular linear regression

2017-07-27 Thread Peter Smits
Hi, If your adventurous you could probably write your own model in R or Stan or similar. The wrapped Normal or the Von Mise distribution are circular and map from 0 to 2pi. My suggestion would be to include a species level phylogenetic "random effect" for the mean parameter to account for the aut

Hi again Frank, I just realized that a sine or cosine transformation would leave you with opposite colors on the hue having the same value... probably not so handy. Sorry, that was a poor suggestion... Florian 2017-07-27 14:09 GMT+02:00 Florian Boucher : > Hi Franz, > > I don't know about anyth

Hi Franz, I don't know about anything like what you propose but maybe you could sine-transform your trait and then use phylogenetic linear or logistic regression? Florian 2017-07-27 13:06 GMT+02:00 f.k...@mailbox.org : > Hi all, > > it there something like a phylogenetic circular linear regress
