Dear all, I am trying to compute the diversification rates as Jetz et al. 2012 ( https://www.nature.com/articles/nature11631), where the authors have said that the formula is the inverse of the equal splits distinctiveness value of Redding and Moors 2006 ( https://onlinelibrary.wiley.com/doi/full/10.1111/j.1523-1739.2006.00555.x). But, in another paper, Pyron & Jetz 2018 ( https://www.nature.com/articles/s41559-018-0515-5) said “is closely inversely related to the equal splits metric”. Looking in both formulas they seem to be the “same” but only the inverse of equal splits, as Jetz et al. said in 2012.
I would like to know if some of you have already calculated this diversification rate and if it is in fact just the inverse, or it is a kind of "closely" related formula. I wrote a small example of what I’ve done, and would like to ask if you think that this is the right way to do that. library(phytools) tr <- rtree(20) plot(tr) tr <- compute.brlen(tr) plot(tr) tr$edge.length tr$edge plot(tr, show.tip.label = TRUE, show.node.label = TRUE) ES = evol.distinct(tr, type = "equal.splits")$w DR = evol.distinct(tr, type = "equal.splits")$w^-1 Thank you in advance, -- Lilian Sayuri Ouchi de Melo (PhD Student in Animal Biology at UNESP/IBILCE) [[alternative HTML version deleted]] _______________________________________________ R-sig-phylo mailing list - Remail@example.com https://stat.ethz.ch/mailman/listinfo/r-sig-phylo Searchable archive at http://firstname.lastname@example.org/
