Indices for Characterizing Ordinal Data

Conference paper


In a well-known approach for the analysis of qualitative data, the information on the objects contained in each (qualitative) variable is represented by a corresponding binary relation on the set of objects. The aim is then to find, for example, a single relation—a median relation—approximating best the input data. Barthelemy and Monjardet (1980/81, 1987) give an excellent overview of the underlying concept, suitable objective functions and solution methods.
