An important role of diagnostic medicine research is to estimate and compare the accuracies of diagnostic tests. This book provides a comprehensive account of statistical methods for the design and analysis of diagnostic studies, including sample size calculations, estimation of the accuracy of a diagnostic test, comparison of accuracies of competing diagnostic tests, and regression analysis of diagnostic accuracy data. This updated edition features edited case studies and new methods, including screening tests, semi-parametric and non-parametric regression models, and SROC and partial areas. Clinicians and advanced students will benefit from this much-needed guide.
