Examples
-
The lack of resolution in more terminal internal nodes is common in studies using phylogenetic supertrees, but these studies also tend to have polytomous nodes basally as well
-
The comparative biology literature on this topic is deeper, focusing on developing methods to deal with soft polytomies by representing the branch lengths between the lineages derived from a polytomous node as a zero
-
The above results show that when large phylogenies are used containing polytomous nodes basally in the tree the researcher may expect to have substantially reduced statistical power to detect non-random phylogenetic community structure.
-
(CIs) in the middle and low titer groups were calculated using a polytomous logistic regression model, with the high titer group considered as control.
