We are pleased to present the report on the 30th Fall Meeting of the working group ``Data Analysis and Numerical Classification'' (AG-DANK) of the German Classification Society. The meeting took place at the Weierstrass Institute for Applied Analysis and Stochastics (WIAS), Berlin, from Friday Nov. 14 till Saturday Nov. 15, 2008. Already 12 years ago, WIAS had hosted a traditional Fall Meeting with special focus on classification and multivariate graphics (Mucha and Bock, 1996). This time, the special topics were stability of clustering and classification, mixture decomposition, visualization, and statistical software.

The working group AG-DANK of the German Classification Society (``Gesellschaft für Klassifikation,'' GfKl) deals with all statistical, mathematical, and computational aspects of data analysis and classification problems (clustering, discriminant analysis, supervised/unsupervised classification, pattern recognition, data mining) and with their applications in the sciences, the economy, engineering, archaeometry, and the administration. The GfKl, founded in the year 1977, is a transdisciplinary scientific society that aims at promoting methods of classification and data analysis in theory and application.

The editors and the working group AG-DANK would like to thank all who have contributed to this report. Our special thanks go to the head of WIAS for their active support and thorough preparation of the event.
