Shrinkage Estimation

By: Dominique Fourdrinier,William E. Strawderman,Martin T. Wells

This book provides a coherent framework for understanding shrinkage estimation in statistics. The term refers to modifying a classical estimator by moving it closer to a target which could be known a priori or arise from a model. The goal is to construct estimators with improved statistical properties. The book focuses primarily on point and loss estimation of the mean vector of multivariate normal and spherically symmetric distributions. Chapter 1 reviews the statistical and decision theoretic terminology and results that will be used throughout the book. Chapter 2 is concerned with estimating the mean vector of a multivariate normal distribution under quadratic loss from a frequentist perspective. In Chapter 3 the authors take a Bayesian view of shrinkage estimation in the normal setting. Chapter 4 introduces the general classes of spherically and elliptically symmetric distributions. Point and loss estimation for these broad classes are studied in subsequent chapters. In particular, Chapter 5 extends many of the results from Chapters 2 and 3 to spherically and elliptically symmetric distributions. Chapter 6 considers the general linear model with spherically symmetric error distributions when a residual vector is available. Chapter 7 then considers the problem of estimating a location vector which is constrained to lie in a convex set. Much of the chapter is devoted to one of two types of constraint sets, balls and polyhedral cones. In Chapter 8 the authors focus on loss estimation and data-dependent evidence reports. Appendices cover a number of technical topics including weakly differentiable functions; examples where Stein’s identity doesn’t hold; Stein’s lemma and Stokes’ theorem for smooth boundaries; harmonic, superharmonic and subharmonic functions; and modified Bessel functions.

Drug Metabolism

Chemical and Enzymatic Aspects

By: Jack P. Uetrecht,William Trager

In order to understand drug metabolism at its most fundamental level, pharmaceutical scientists must be able to analyze drug compound structure and predict possible metabolic pathways in order to avoid the risk of adverse reactions that lead to the withdrawal of a drug from the market. This title is a comprehensive guide for recognizing the chemica

9/11 and the Future of Transportation Security

By: R. William Johnstone

R. William Johnstone served on the transportation security staff of the 9/11 Commission, and wrote this book to build upon and supplement the Commission's work. In its pages, he explains the aviation security system failure on 9/11, uses that as a means for evaluating post-9/11 transportation security efforts, and proposes remedies to continued shortcomings. 9/11 and the Future of Transportation Security is based on information originally provided to the 9/11 Commission, augmented by unpublished reports and a wealth of other material that has come to light since the issuance of the Commission's own report in July 2004. Part One analyzes the aviation security system's history and institutions to explain why the system failed on 9/11. Part Two looks at what has been done in aviation and transportation security since 9/11, including the Commission's recommendations and the congressional response to them. Finally and most significantly, Part Three outlines a suggested approach for improving current U.S. transportation security. It begins with fundamental policy questions that must be answered if we are to optimize transportation security efforts, and concludes with both underlying principles for action and specific recommendations.

Effective Psychotherapists

By: William R. Miller,Theresa B. Moyers

What is it that makes some therapists so much more effective than others, even when they are delivering the same evidence-based treatment? This instructive book identifies specific interpersonal skills and attitudes--often overlooked in clinical training--that facilitate better client outcomes across a broad range of treatment methods and contexts. Reviewing 70 years of psychotherapy research, the preeminent authors show that empathy, acceptance, warmth, focus, and other characteristics of effective therapists are both measurable and teachable. Richly illustrated with annotated sample dialogues, the book gives practitioners and students a blueprint for learning, practicing, and self-monitoring these crucial clinical skills.
