j_one

The \(J^1\) index calculates the Shannon Entropy of a tree,
where at each node with two children, the Shannon Entropy is the sum of
\(p_i log_2(p_i)\) over the two children \(i\), and \(p_i\) is
\(L / (L + R)\),
where L and R represent the number of tips connected to the two daughter
branches.

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>.
