Praise for the First Edition: "If you . . . want an up-to-date, definitive reference writtenby authors who have contributed much to this field, then this bookis an essential addition to your library." —Journal of the American StatisticalAssociation Fully updated to reflect the major progress in the use ofstatistically designed experiments for product and processimprovement, Experiments, Second Edition introduces some ofthe newest discoveries—and sheds further light on existingones—on the design and analysis of experiments and theirapplications in system optimization, robustness, and treatmentcomparison. Maintaining the same easy-to-follow style as theprevious edition while also including modern updates, this bookcontinues to present a new and integrated system of experimentaldesign and analysis that can be applied across various fields ofresearch including engineering, medicine, and the physicalsciences. The authors modernize accepted methodologies while refining manycutting-edge topics including robust parameter design, reliabilityimprovement, analysis of non-normal data, analysis of experimentswith complex aliasing, multilevel designs, minimum aberrationdesigns, and orthogonal arrays. Along with a new chapter thatfocuses on regression analysis, the Second Edition featuresexpanded and new coverage of additional topics, including: Expected mean squares and sample size determination One-way and two-way ANOVA with random effects Split-plot designs ANOVA treatment of factorial effects Response surface modeling for related factors Drawing on examples from their combined years of working withindustrial clients, the authors present many cutting-edge topics ina single, easily accessible source. Extensive case studies,including goals, data, and experimental designs, are also included,and the book's data sets can be found on a related FTP site, alongwith additional supplemental material. Chapter summaries provide asuccinct outline of discussed methods, and extensive appendicesdirect readers to resources for further study. Experiments, Second Edition is an excellent book fordesign of experiments courses at the upper-undergraduate andgraduate levels. It is also a valuable resource for practicingengineers and statisticians.

Die zugrunde liegenden Prinzipien, erfunden und entwickelt von Dr. Genichi Taguchi (1924-2012), zum Entwurf von Experimenten oder Simulationsrechungen in vielparametrischen Systemen, werden heute als Taguchi Methode bezeichnet. Durch den großen Erfolg wurde sie auf viele andere Bereiche erweitert. In diesem Buch werden die Grundlagen dieser Methode so ausführlich wie geboten und so einfach und anschaulich wie möglich dargelegt. Dabei zeigt der Autor, wie breit gefächert das heutige Anwendungsspektrum ist und für welche unterschiedlichen Aufgabenstellungen sie eingesetzt werden kann. Die Anwendungsbeispiele reichen von der Optimierung eines Fermentationsprozesses in der Biotechnologie über die Kostenminimierung in der mechanischen Fertigung bis zur Erhaltung und Verbesserung der Konkurrenzfähigkeit in der industriellen Produktion. Das Buch gliedert sich in drei Teile. Im ersten Teil führt der Autor in die methodischen Grundlagen ein – immer unter Berücksichtigung der Zusammenhänge von Kosten, Präzision und Spezifikationen. Der zweite Teil beschäftigt sich mit Mustererkennung. Abweichende Muster können nach der Taguchi-Methode mit hoher Trennschärfe unterschieden und als Kollisionswarnung beim automatisierten Fahren, als Authentifizierung oder auch in der medizinischen Diagnostik und Therapeutik umgesetzt werden, wie die Fallbeispiele verdeutlichen. Im dritten Teil zeigt der Autor das Potenzial der Methodik für die Erstellung von Prognosen, ob im Kontext industrieller Anwendungen, für die Vorhersage von Krankheitsverläufen in der Medizin oder für das Eintreten von Naturereignissen. Der Band enthält zahlreiche vollständige numerische Fallbeispiele, wobei die Berechnungen durch Abbildungen oder Diagramme veranschaulicht werden. Im Anhang finden Leser eine ausführliche Darstellung der Theorie, so dass sie theoretische Fragen bei Bedarf vertiefen können. Studierende, Wissenschaftler, Ingenieure oder Entwicklungs- und Produktverantwortliche lernen mit dem Buch die Taguchi Methode anzuwenden – auch ohne mathematisch-statistisches Vorwissen. Diese geschilderten Verfahren sind bestens geeignet, um relativ schnell zuverlässige und präzise Lösungen für die unterschiedlichsten Problemstellungen zu finden. Ein echter Wettbewerbsvorteil in der Forschung oder für Unternehmen, die im internationalen Wettbewerb konkurrenzfähig bleiben wollen.

Many problems in statistics and econometrics offer themselves naturally to the use of optimization heuristics. Standard methods applied to highly complex problems often produce approximate results, of unknown quality, based on heavy assumptions. Optimization heuristic methods provide powerful results to many complex problems, combined with relatively simple implementation. The techniques used in optimization heurisitics can be applied to problems encountered in econometrics, statistics and operations research. * Offers a self-contained introduction to optimization heuristics in econometrics and statistics * Features many examples of optimization heuristic methods applied to real problems * Includes detailed coverage of the threshold accepting heuristic methods applied to real problems * Provides suggestions for further reading Split into three parts, the book opens with a general introduction to optimization in statistics and econometrics, followed by detailed discussion of a relatively new and very powerful optimization heuristic, threshold accepting. The final part consists of many applications of the methods described earlier, encompassing experimental design, model selection, aggregation of time series, and censored quantile regression models. Those researching and working in econometrics, statistics and operations research are given the tools to apply optimization heuristic methods to real problems in their work. Postgraduate students of statistics and econometrics will find the book provides a good introduction to optimization heuristic methods.

The authoritative reference on nonparametric methods for evaluating longitudinal data in factorial designs Broadening the range of techniques that can be used to evaluate longitudinal data, Nonparametric Analysis of Longitudinal Data in Factorial Experiments presents nonparametric methods of evaluation that supplement the generalized linear models approach. Emphasizing the practical application of these methods in statistical procedures, this book provides a unified approach for the analysis of factorial designs involving longitudinal data that is appropriate for metric data, count data, ordered categorical data, and dichotomous data. Topics covered include nonparametric models, effects and hypotheses in experimental design, estimators for relative effects, experiments for one and several groups of subjects, multifactorial experiments, dependent replications, and experiments with numerous time points. The basic mathematical principles for the methods introduced here are described in theory, consistent with the book's minimal math requirements. Simple approximations for small data sets are provided, as well as ample chapter exercises to test skills, an appendix that includes original data for the examples used throughout the book, and downloadable SAS-IML macros for implementing the more extensive calculations. All applications are designed to be useful in many fields. Generously supplemented with more than 110 graphs and tables, Nonparametric Analysis of Longitudinal Data in Factorial Experiments is an essential reference for statisticians and biometricians, researchers in clinical trials, psychological studies, and in the fields of forestry, agriculture, sociology, ecology, and biology, as well as graduate students in statistics and biostatistics.

Statistical Analysis of Observations of Increasing Dimension is devoted to the investigation of the limit distribution of the empirical generalized variance, covariance matrices, their eigenvalues and solutions of the system of linear algebraic equations with random coefficients, which are an important function of observations in multidimensional statistical analysis. A general statistical analysis is developed in which observed random vectors may not have density and their components have an arbitrary dependence structure. The methods of this theory have very important advantages in comparison with existing methods of statistical processing. The results have applications in nuclear and statistical physics, multivariate statistical analysis in the theory of the stability of solutions of stochastic differential equations, in control theory of linear stochastic systems, in linear stochastic programming, in the theory of experiment planning.
