Scan 2000, the GAMM - IMACS International Symposium on Scientific Computing, Computer Arithmetic, and Validated Numerics and Interval 2000, the International Conference on Interval Methods in Science and Engineering were jointly held in Karlsruhe, September 19-22, 2000. The joint conference continued the series of 7 previous Scan-symposia under the joint sponsorship of GAMM and IMACS. These conferences have traditionally covered the numerical and algorithmic aspects of scientific computing, with a strong emphasis on validation and verification of computed results as well as on arithmetic,...

This Festschrift is dedicated to Gotz Trenkler on the occasion of his 65th birthday. As can be seen from the long list of contributions, Gotz has had and still has an enormous range of interests, and colleagues to share these interests with. He is a leading expert in linear models with a particular focus on matrix algebra in its relation to statistics. He has published in almost all major statistics and matrix theory journals. His research activities also include other areas (like nonparametrics, statistics and sports, combination of forecasts and magic squares, just to mention afew). Gotz...

Der Band bietet eine allgemein verstandliche Ubersicht uber 100 Jahre Deutsche Statistische Gesellschaft (DStatG). In 17 Kapiteln schildern anerkannte Experten, wie die DStatG zur Begrundung und Fortentwicklung der deutschen Wirtschafts- und Sozialstatistik und zu methodischen Innovationen wie neuere Zeitreihen-, Preisindex- oder Stichprobenverfahren beigetragen hat. Weitere Themen sind die Rolle der DStatG bei der Zusammenfuhrung der Ost- und Weststatistik sowie die Vorbereitung und Durchfuhrung der letzen und der aktuellen Volkszahlung."

Das Buch nimmt die aktuelle Wirtschaftskrise zum Anlass, um die Frage nach der Qualitat der Presse, insbesondere der der Tageszeitungen zu stellen. Herzstuck des Buches sind aktuelle Beispiele, die veranschaulichen, dass Journalisten zu oft die Bedurfnisse der Leser missachten und schwer verstandliche Texte oder Uberschriften produzieren, die haufig nicht einmal interessant sind. Wer immer schon mal wissen wollte, warum ihn Wirtschaftstexte abschrecken, bekommt hier Antworten. Das Autorengespann zeigt gangige Auswahlfehler und kritisiert den Hang zum Dramatisieren und das Primat der...

Econometric models are made up of assumptions which never exactly match reality. Among the most contested ones is the requirement that the coefficients of an econometric model remain stable over time. Recent years have therefore seen numerous attempts to test for it or to model possible structural change when it can no longer be ignored. This collection of papers from Empirical Economics mirrors part of this development. The point of departure of most studies in this volume is the standard linear regression model Yt = x;fJt + U (t = I, ..., 1), t where notation is obvious and where the index...
