Calculates the number of moves required to transform the focal tree into a fully imbalanced (caterpillar) tree. Higher value indicates a more balanced tree.

Usage

imbalance_steps(input_obj, normalization = FALSE)

Arguments

input_obj

phylo object or ltable

normalization

if true, the number of steps taken is normalized by tree size, by dividing by the maximum number of moves required to move from a fully balanced to a fully imbalanced tree, which is \(N - log2(N) - 1\), where N is the number of extant tips.

Value

required number of moves
