Evidence - its nature and interpretation - is the key to many topical debates and concerns such as global warming, evolution, the search for weapons of mass destruction, DNA profiling, evidence-based medicine. In 2004 University College London launched a cross-disciplinary research programme "Evidence, Inference and Enquiry" to explore the question: "Can there be an integrated multidisciplinary science of evidence?" While this question was hotly contested and no clear final consensus emerged, much was learned on the journey. This book, based on the closing conference of the programme held at the British Academy in December 2007, illustrates the complexity of the subject, with 17 chapters written from a diversity of perspectives including Archaeology, Computer Science, Economics, Education, Health, History, Law, Psychology, Philosophy and Statistics. General issues covered include principles and systems for handling complex evidence, evidence for policy-making, and human evidence-processing, as well as the very possibility of systematising the study of evidence.

WINNER OF THE 2001 DEGROOT PRIZE!Probabilistic expert systems are graphical networks that support the modelling of uncertainty and decisions in large complex domains, while retaining ease of calculation. Building on original research by the authors over a number of years, this book gives a thorough and rigorous mathematical treatment of the underlying ideas, structures, and algorithms, emphasizing those cases in which exact answers are obtainable. It covers both the updating of probabilistic uncertainty in the light of new evidence, and statistical inference, about unknown probabilities or unknown model structure, in the light of new data. The careful attention to detail will make this work an important reference source for all those involved in the theory and applications of probabilistic expert systems.This book was awarded the first DeGroot Prize by the International Society for Bayesian Analysis for a book making an important, timely, thorough, and notably original contribution to the statistics literature.

A state of the art volume on statistical causalityCausality: Statistical Perspectives and Applications presents a wide-ranging collection of seminal contributions by renowned experts in the field, providing a thorough treatment of all aspects of statistical causality. It covers the various formalisms in current use, methods for applying them to specific problems, and the special requirements of a range of examples from medicine, biology and economics to political science.This book: Provides a clear account and comparison of formal languages, concepts and models for statistical causality.Addresses examples from medicine, biology, economics and political science to aid the reader's understanding.Is authored by leading experts in their field.Is written in an accessible style.Postgraduates, professional statisticians and researchers in academia and industry will benefit from this book.

Several points of disagreement exist between different modelling traditions as to whether complex models are always better than simpler models, as to how to combine results from different models and how to propagate model uncertainty into forecasts. This book represents the result of collaboration between scientists from many disciplines to show how these conflicts can be resolved.Key Features: Introduces important concepts in modelling, outlining different traditions in the use of simple and complex modelling in statistics. Provides numerous case studies on complex modelling, such as climate change, flood risk and new drug development. Concentrates on varying models, including flood risk analysis models, the petrol industry forecasts and summarizes the evolution of water distribution systems. Written by experienced statisticians and engineers in order to facilitate communication between modellers in different disciplines. Provides a glossary giving terms commonly used in different modelling traditions. This book provides a much-needed reference guide to approaching statistical modelling. Scientists involved with modelling complex systems in areas such as climate change, flood prediction and prevention, financial market modelling and systems engineering will benefit from this book. It will also be a useful source of modelling case histories.
