wiener

The Wiener index is defined as the sum of all shortest path
lengths between pairs of nodes in a tree.

Collection of phylogenetic tree statistics,
collected throughout the literature. All functions have been
written to maximize computation speed. The package includes
umbrella functions to calculate all statistics, all balance
associated statistics, or all branching time related statistics.
Furthermore, the 'treestats' package supports summary statistic
calculations on Ltables, provides speed-improved coding of
branching times, Ltable conversion and includes algorithms to
create intermediately balanced trees. Full description can be
found in Janzen (2024) <doi:10.1016/j.ympev.2024.108168>.
