This book presents a collection of papers presented at the biannual meeting of the Classification and Data Analysis Group of Società Italiana di Statistica, held in Rome in July 1999. The papers were selected after a careful review process and are organized into four parts: Classification and Multidimensional Scaling, Multivariate Data Analysis, Spatial and Time Series Data Analysis, and Applications and Case Studies. The topics covered include classification theory, multivariate data analysis, proximity structure analysis, software developments, and applied classification and data analysis. The book also includes a preface, acknowledgments, and a contents list. The authors are from various universities and research institutions in Italy and abroad. The book is part of a series on classification, data analysis, and knowledge organization, published by Springer. The book includes 45 papers, with each paper being a contribution to the field of classification and data analysis. The papers cover a wide range of topics, including clustering, discriminant analysis, multidimensional scaling, factorial methods, textual data analysis, regression models, nonparametric methods, time series analysis, spatial data analysis, and applications in various fields such as economics, quality control, environmental science, medical science, and demography. The book is intended for researchers and practitioners in the fields of statistics, data analysis, and classification. The book is published by Springer-Verlag and is available in multiple languages. The book includes 66 figures and 94 tables. The book is part of the "Studies in Classification, Data Analysis, and Knowledge Organization" series. The book is indexed in the German Cataloging-in-Publication Data. The book is also available in electronic format. The book is dedicated to the International Federation of Classification Societies (IFCS), which is an organization that promotes the dissemination of technical and scientific information related to classification and data analysis. The book is a contribution to the ongoing development of classification and data analysis methods. The book is a valuable resource for researchers and practitioners in the fields of statistics, data analysis, and classification. The book is a comprehensive overview of the current state of research in classification and data analysis.
