Riassunto:
This introductory volume includes worked examples from a variety of data sets about the most frequently used models and computer programs for MDS, as well as techniques for collecting data and assessing MDS results. It covers the design, execution, and analysis of multidimensional scaling experiments and includes detailed descriptions and examples of six major MDS computer programs: MINISSA, POLYCON, KYST, INDSCAL/SINDSCAL, ALSCAL and MULTISCALE. These six approaches are sufficiently fundamental that continuing developments in the field will build on the principles presented in this volume.
