Overview

Presents a new, modern approach to measurement error in continuous explanatory variables and misclassification in categorical explanatory variables Discusses the Bayesian impacts on measurement error-the first book to do so Contains a balance of basic pedagogic and research-oriented material Unifies the epidemiology and statistics literature on the subject, making it accessible to researchers in both field Presents technical and mathematical details at the end of each chapter to make the book easy to use This book addresses the challenge of accurately measuring explanatory variables, a common problem in biostatistics and epidemiology. The author explores both measurement error in continuous variables and misclassification in categorical variables. He also describes the circumstances in which it is necessary to explicitly adjust for imprecise covariates using the Bayesian approach and a Markov chain Monte Carlo algorithm. The book offers a mix of basic and more specialized topics such as "wrong-model" fitting. Mathematical details are featured in the final sections of each chapter. Because of its dual approach, the book is a useful reference for biostatisticians, epidemiologists, and students.
