Analysis of Symbolic Data (eBook, PDF)

Exploratory Methods for Extracting Statistical Information from Complex Data
Redaktion: Bock, Hans-Hermann; Diday, Edwin

• Format: PDF

Produktbeschreibung

This book presents the most recent methods for analyzing and visualizing symbolic data. It generalizes classical methods of exploratory, statistical and graphical data analysis to the case of complex data. Several benchmark examples from National Statistical Offices illustrate the usefulness of the methods. The book contains an extensive bibliography and a subject index.
