Computes quantitative Kulczynski distances between the columns of an abundance matrix.
(non-negative) abundance matrix. Columns are species, rows are regions.
The quantitative Kulczynski distance between two species is 1-(mean of (mean of over regions minimum abundance of both species)/(sum of abundances of species 1) and (mean of over regions minimum abundance of both species)/(sum of abundances of species 2)). If the abundance matrix is a 0-1-matrix, this gives the standard Kulczynski distance.
A symmetrical matrix of quantitative Kulczynski distances.
