bw.nn: nearest-neighbor adaptive bandwidth selection

Description

For each row in pairwise distance matrix find the distance to the closest prop fraction of trees.

Usage

bw.nn(x, prop = 0.2, tol = 1e-06)

Arguments

x

pairwise distance matrix

prop

fraction of data to define the local neighborhood

tol

tolerance for zero-bandwidth check

Value

• a vector of bandwidths for each tree (row) in x

Examples

dm <- as.matrix(dist.diss(apicomplexa[1:20]))
bw.nn(dm)
