Abstract
Multidimensional Scaling (MDS) is a data analysis technique to represent a set of objects in a multidimensional space in such a way that points corresponding to similar objects are close together and points corresponding to dissimilar objects are located far apart. Asymmetric MDS is an extension of the ordinary MDS to consider asymmetric relationships. A variety of models and methods have been proposed to capture asymmetry, in this paper a brief review will be presented focalizing on graphical capabilities. As it will be shown, a key role in the development of models and methods for the analysis of asymmetry in MDS was played by two papers written by John Gower in the Seventies.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
