Fichet, B.; le Calve, G.
Structure géométrique des principaux indices de dissimilarité sur signes de présence-absence. (French)
[J] Stat. Anal. Données 9, No.3, 11-44 (1984). ISSN 0750-7364

Summary: Considering the usual similarity coefficients s for logical data (presence-absence of characters) and the associated dissimilarities d such that $d=1-s$, the authors study the geometrical nature of dissimilarity coefficients d and $\sqrt{d}$, with respect to their metric and Euclidean structures.

MSC 2000:: *62H30 Statistical classification, etc.

Keywords: distance; approximation; positive semi-definite matrices; similarity coefficients; dissimilarity coefficients; Euclidean structures
