buttler_fickel_dist

Computes a distance matrix following Buttler &amp; Fickel (1995) for mixed-scale
variables. Each variable-specific distance matrix is normalized by its mean
pairwise distance (Gini mean difference), ensuring equal contribution of all
variables to the overall distance.

Implements the distance measure for mixed-scale variables proposed by
Buttler and Fickel (1995), based on normalized mean pairwise distances
(Gini mean difference), and an R2 statistic to assess clustering quality.
