Multidimensional scaling and distance matrices
...trix but a kinship one. If Statistica transformed the kinship matrix
into a distance one (how?) is anybody's guess.
A quick search immediately showed that a multidimensional scaling is
done on a distance matrix. See for instance:
MASS4, pg 304
"Elements of computational statistics", Jentle, pg 122
Edwards and Oman's article, page 2-7 R-News 3/3
The fact that Statistica happily perform MDS on a "kinship" matrix is
puzzling. Indeed, I would expect errors, as in the following toy
example, without transforming the kinship matrix to distances:
