This expanded and updated second edition builds upon the success of its predecessor in providing a concise, practical and yet relatively non-technical account of those more sophisticated statistical techniques now used routinely in many medical investigations. The new edition gives additional space to such important topics as the design of medical investigations, regression and logistic regression, the analysis of longitudinal studies, the problems of missing data, and the analysis of observational studies. All chapters include new examples. Statistical Methods for Medical Investigations is aimed at medical statisticians and other researchers working in the medical field.rnIncludes bibliographical references 9p. [219]-232) and index.
