Stock Market Science vs. Myth: How to Test Before You Invest

(Many popular stock-trading rules of thumb and trading sys...)

Many popular stock-trading rules of thumb and trading systems tested in this book are unreliable. The tales of their effectiveness are myths. The book reveals new scientifically tested stock trading systems that more than double certain investment returns compared to buying and holding certain equities. To illustrate the effectiveness of the new systems and ineffectiveness of the mythical trading systems, the thirty stocks in the Dow Jones Industrial Average (Djia), twenty-six older exchange traded funds (Etfs) that reflect prices of various U.S. and foreign market indices, and the ten most popular mutual funds are used as examples. Readers of the book learn how to evaluate trading systems and test their own ideas based on scientific methods using free software downloaded from the author's website on the Internet. "Robertson is a worthy guide who can bring difficult concepts to the level of even the casual investor." Dan Shearer, Editor, Green Valley News (Arizona)

Injury Epidemiology: Fourth edition

(Research on injuries is a high priority to inform public ...)

Research on injuries is a high priority to inform public policy that reduces deaths, hospitalizations and associated costs. Principles for research design and analysis of injury incidence and severity are emphasized. Review of extant surveillance data reveals numerous flaws that must be changed to increase usefulness of the data. Research designs of studies of injury causation and evaluation of countermeasures are often inappropriate and mislead analytic and injury control efforts. Appendices to chapters illustrate research projects that influenced public policy affecting the reduction of motor vehicle fatalities per population by half in the U.S. The principles illustrated by these studies can be applied to other types of injury.

Injury Epidemiology

This text presents epidemiologic methods for studying injuries and evaluating interventions to prevent them. It explains the formation of research questions, the sources of reliable and valid data, and the choice of research methods. The difficulties of applying rates and ratios to the evaluation of programs are discussed, and the use of economic concepts and policy analysis is covered. The Second Edition provides specific objectives for research needed in the various stages of injury control planning and implementation, including the types of data needed to reach the objectives. In a progressive, step-by-step analysis, the posing of research questions and the research designs that best answer those questions are illustrated. Examples of the use of surveillance systems to direct allocation of countermeasures of known effectiveness are updated. The false nexus between causation and prevention is clarified and the notion of the causal web is demystified. New studies of the effects of behavioral interventions, laws, and regulations are reviewed. The increasing gap between what is known and what is assumed in regulatory and cost-benefit analyses is discussed.

The previous edition of this useful text on epidemiologic methods for studying injuries and evaluating interventions to prevent them provides specific objectives for research in the various stages of injury control planning and implementation, including the types of data needed to reach the objectives. Using a progressive, step-by-step analysis, it illustrates how to pose research questions and design the best research studies to answer those questions. This new edition will update all chapters and include new examples of studies. The chapters will also be organized into more precise topic areas for ease of reference. The chapter on policy analysis would be dissolved and topic treated as part of other chapters.
