Der vorliegende Band faßt die Ergebnisse eines zweitägigen Symposions "Multiple Hypothesenprüfung" am 6. und 7. November 1987 in Gerolstein/ Eifel zusammen. Das Problem der multiplen Hypothesenprüfung stellt sich immer dann, wenn aufgrund eines statistischen Experimentes mehrere Fragestellungen beantwortet werden sollen. Insbesondere innerhalb biologisch-medizi nischer Studien sind häufig mehrere Behandlungen, mehrere Zielgrößen oder Messungen zu mehreren Zeitpunkten zu beurteilen. In der Vergangenheit wurde dem Problem der Multiplizität der Fragestel lungen nicht genügend Beachtung geschenkt. Im deutschsprachigen Raum erschien dieses Thema etwa ab Ende der 70er Jahre vermehrt auf Kongres sen sowie in Veröffentlichungen, ausgelöst durch die Arbeiten von MARCUS, PERITZ und GABRIEL (1976) und HOLM (1979). Besonders durch das Schwerpunkuhema "Simultane Hypothesenprüfung" und die gemein same Publikation der Referate im Rahmen des Biometrischen Seminars im Jahre 1981 in Bad Ischl, Österreich, wurde die Aufmerksamkeit vieler Biometriker auf neuere Entwicklungen in diesem für die Anwendung so wichtigen Bereich gelenkt. In der Folge kam es zu einer intensiven For schungstätigkeit an den verschiedensten Stellen, vorwiegend von Biometr- kern und von Statistikern mit engem Verhältnis zur Biometrie. Es war daher naheliegend zu versuchen, die in diesem Bereich methodisch tätigen Biometriker und Statistiker zu einem intensiven Meinungsaus tausch zusammenzubringen. Dabei sollte eine Bestandsaufnahme vorge nommen und über die Richtung weiterer Entwicklungen diskutiert werden. Schon während des Symposions wurde von emlgen Teilnehmern der Vor schlag gemacht, den Tagungsband in englischer Sprache abzufassen, um IV den Ergebnissen international eine größere Verbreitung zu ermöglichen.

Written by experts that include originators of some key ideas, chapters in the Handbook of Multiple Testing cover multiple comparison problems big and small, with guidance toward error rate control and insights on how principles developed earlier can be applied to current and emerging problems. Some highlights of the coverages are as follows. Error rate control is useful for controlling the incorrect decision rate. Chapter 1 introduces Tukey's original multiple comparison error rates and point to how they have been applied and adapted to modern multiple comparison problems as discussed in the later chapters. Principles endure. While the closed testing principle is more familiar, Chapter 4 shows the partitioning principle can derive confidence sets for multiple tests, which may become important as the profession goes beyond making decisions based on p-values. Multiple comparisons of treatment efficacy often involve multiple doses and endpoints. Chapter 12 on multiple endpoints explains how different choices of endpoint types lead to different multiplicity adjustment strategies, while Chapter 11 on the MCP-Mod approach is particularly useful for dose-finding. To assess efficacy in clinical trials with multiple doses and multiple endpoints, the reader can see the traditional approach in Chapter 2, the Graphical approach in Chapter 5, and the multivariate approach in Chapter 3. Personalized/precision medicine based on targeted therapies, already a reality, naturally leads to analysis of efficacy in subgroups. Chapter 13 draws attention to subtle logical issues in inferences on subgroups and their mixtures, with a principled solution that resolves these issues. This chapter has implication toward meeting the ICHE9R1 Estimands requirement. Besides the mere multiple testing methodology itself, the handbook also covers related topics like the statistical task of model selection in Chapter 7 or the estimation of the proportion of true null hypotheses (or, in other words, the signal prevalence) in Chapter 8. It also contains decision-theoretic considerations regarding the admissibility of multiple tests in Chapter 6. The issue of selected inference is addressed in Chapter 9. Comparison of responses can involve millions of voxels in medical imaging or SNPs in genome-wide association studies (GWAS). Chapter 14 and Chapter 15 provide state of the art methods for large scale simultaneous inference in these settings.

Describes the most important methods used to investigate differences between levels of an independent variable within an experimental design. Readers will learn not only how to conduct multiple comparisons in experimental designs but also how to better understand and evaluate published research. "A highly readable introduction to multiple comparison methods, which demands little from its reader in the way of background other than some familiarity with analysis of variance." --The Statistician

This book provides readers with essential information on the foundations of psychotherapy research, and on its applications to the study of both psychotherapy process and outcome. The aim is to stimulate a reflection on these issues in a way that will benefit researchers and clinicians, as well as undergraduate and graduate students, at different levels and from different perspectives. Accordingly, the book presents a balanced mix of chapters summarizing the state of the art in the field from different viewpoints and covering innovative topics and perspectives, reflecting some of the most established traditions and, at the same time, emerging approaches in the field in several countries. The contributors, who were invited from among the experts in our national and international professional networks, also represent a healthy mix of leading figures and young researchers. The first part of the book addresses a number of fundamental issues in psychotherapy research at a historical, philosophical, and theoretical level. The second part of the book is concerned with research on psychotherapy processes; in this regard, both quantitative and qualitative approaches are given equal consideration in order to reflect the growing relevance of the latter. The book’s third and last part examines research on psychotherapy outcomes, primarily focusing on quantitative approaches. Offering a balanced mix of perspectives, approaches and topics, the book represents a valuable tool for anyone interested in psychotherapy research.
