Summary Statistic Reference Description
T - The total length of all branches of the tree.
t MRCA - The difference in age between the most recent common ancestor and the most modern individual.
D F [2] A classic summary statistic for testing neutrality. Normalized difference between external branch lengths and total tree length.
B 1 [34] A measure of tree-imbalance.
C n [20] The number of internal nodes with exactly two terminal children(the number of cherries).
I c [18] A measure of tree-imbalance. Ranges is [0,1]. Larger numbers signify more imbalanced trees.
