This statistic calculates per tip, the sum of the inverse of all branch lengths of the shortest path between the root and the tip.

Usage

inv_branch_dist(phy, add_one = FALSE)

Arguments

phy

phylo object or ltable

add_one

should we take 1 / bl or 1 / (1 + bl) ? if TRUE, then 1 / (1 + bl) is used. Default: FALSE.
