Statistical Power Analysis is a nontechnical guide to power analysis in research planning that provides users of applied statistics with the tools they need for more effective analysis. The Second Edition includes: * a chapter covering power analysis in set correlation and multivariate methods;* a chapter considering effect size, psychometric reliability, and the efficacy of "qualifying" dependent variables and;* expanded power and sample size tables for multiple regression/correlation.

Arising from the Cohens' work on the epidemiology of childhood psychopathology, this book explores the two aspects of motivational structure--ideas and values--that underlie the development of maladaptive functioning and symptoms. The first aspect is a measure of what children admire in their peers; this measure is seen as an operationalization of personal ideals. The second is a measure of life goals, seen as a representation of the contemporary structure of long-term personal values.Despite the considerable amount of attention given in the popular press and among social critics and politicians, values have been relatively neglected as a topic of empirical research in this country. To fill the void, this work uses data from a large cohort of young people who have been studied longitudinally since early childhood to elucidate three aspects of life goals and values:* What are the demographic, family, peer, school, and intrapersonal influences that shape values and life goals of adolescents?* How do they change over the course of adolescence?* What impact do these values have on the lives of adolescents and young adults?Decisions about what we find most admirable and which of the many apparently good things in life we will take on as our top priorities are consequential both for the contemporary and for the future emotional and behavioral well-being of the individual. Thus, this book explores systematically the environmental origins of ideals and values, using deprivation and attainment hypotheses to examine a variety of influences on the development of differences in values. This book also examines the relationship between the measures of children's values and psychopathology, examining both the "Axis 1" diagnosis, including disruptive behavior disorders, depression, and anxiety, and the "Axis 2" personality disorders.Providing an extensive study of the life values of adolescents and the state of their mental health, this monograph will be of interest to developmental psychologists specializing in adolescence, child clinical psychologists, and psychiatrists.

This classic text on multiple regression is noted for its nonmathematical, applied, and data-analytic approach. Readers profit from its verbal-conceptual exposition and frequent use of examples.The applied emphasis provides clear illustrations of the principles and provides worked examples of the types of applications that are possible. Researchers learn how to specify regression models that directly address their research questions. An overview of the fundamental ideas of multiple regression and a review of bivariate correlation and regression and other elementary statistical concepts provide a strong foundation for understanding the rest of the text. The third edition features an increased emphasis on graphics and the use of confidence intervals and effect size measures, and an accompanying website with data for most of the numerical examples along with the computer code for SPSS, SAS, and SYSTAT, at www.psypress.com/9780805822236 . Applied Multiple Regression serves as both a textbook for graduate students and as a reference tool for researchers in psychology, education, health sciences, communications, business, sociology, political science, anthropology, and economics. An introductory knowledge of statistics is required. Self-standing chapters minimize the need for researchers to refer to previous chapters.

Corporate Financial Reporting Analysis combines comprehensive coverage and a rigorous approach to modern financial reporting with a readable and accessible style. Merging traditional principles of corporate finance and accepted reporting practices with current models enable the reader to develop essential interpretation and analysis skills, while the emphasis on real-world practicality and methodology provides seamless coverage of both GAAP and IFRS requirements for enhanced global relevance. Two decades of classroom testing among INSEAD MBA students has honed this text to provide the clearest, most comprehensive model for financial statement interpretation and analysis; a concise, logically organized pedagogical framework includes problems, discussion questions, and real-world case studies that illustrate applications and current practices, and in-depth examination of key topics clarifies complex concepts and builds professional intuition. With insightful coverage of revenue recognition, inventory accounting, receivables, long-term assets, M&A, income taxes, and other principle topics, this book provides both education and ongoing reference for MBA students.
