root_imbalance

Measures the distribution of tips over the two crown lineages,
e.g. \(n1 / (n1 + n2)\), where n1 is the number of tips connected to crown
lineage 1 and n2 is the number of tips connected to crown lineage 2. We
always take n1 &gt; n2, thus root imbalance is always in [0.5, 1].

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>.
