entropy_j: Intensive quadratic entropy statistic J.
In treestats: Phylogenetic Tree Statistics
entropy_j R Documentation
Intensive quadratic entropy statistic J.
Description
The intensive quadratic entropy statistic J is given by the
average distance between two randomly chosen species, thus given by the
sum of all pairwise distances, divided by S^2, where S is the number of tips
of the tree.
Usage
entropy_j(phy)
Arguments
phy
phylo object or ltable
Value
intensive quadratic entropy statistic J
