computeKruskalStress: Computation of the Kruskal Stress

Description Usage Arguments Details Value

Description

This function is used to compute the Kruskal Stress between two distance matrices, which quantifies the global quality of a MDS representation.

The Kruskal Stress corresponds to the quantify of information lost during the dimentionality reduction process.

Usage

1
computeKruskalStress(dist1, dist2)

Arguments

dist1

a numeric matrix of the first distance matrix

dist2

a numeric matrix of the second distance matrix

Details

This function has been implemented in C++ for fast computations and can be executed from R using this wrapper.

Value

a numeric value the Kruskal Stress
