NONEUC: a numerical procedure for determining optimum euclidian distances and associated coordinates from distances derived from similarity coefficients
Numerical optimization techniques are applied to derive, from an input matrix of non-euclidian interspecific distances, a set of species coordinates in a multi-dimensional space. The euclidian distances corresponding to these derived species coordinates constitute an optimum fit to the input matrix of non-euclidian rational distances, which are derived from similarity coefficients relating the species in question.
