Reflects both the conceptual development of this evolving science and the increasingly focal role that epidemiology plays in dealing with public health and medical problems. This book covers a range of concepts and methods, including epidemiologic measures of occurrence and effect, study designs, validity, precision, and causal diagrams.

This text provides the first-ever compilation of bias analysis methods for use with epidemiologic data. It guides the reader through the planning stages of bias analysis, including designing validation studies and collecting validity data from other sources.
