So I tried a 12-taxon fully pectinate tree with Blomberg's K as calculated
by picante::Kcalc()
library(picante)
library(ape)
aa<-"(A,(B,(C,(D,(E,(F,(G,(H,(I,(J,(K,L)));"
t1<-read.tree(text=aa)
t4 <- compute.brlen(t1,method="Grafen",1)
tipvals <- c(0,1,0,1,0,1,0,1,0,1,0,1)
Hi all,
I'm interested in the distribution of a non-heritable binary
trait/observation across a large tree 1000+ tip tree. The tree is
non-distinct in shape and balance, it is neither fully pectinate nor fully
balanced. It has many soft polytomies too.
I believe the distribution of this trait to
Ross,
An interesting question. I understand it as that you want to test if
the trait is overdispersed relative to phylogeny, which still makes me
think that measures of 'phylogenetic signal' might be still be useful,
even though the typical interpretation is 'signal' as 'heritability'.
I would
