Group Sequential Methods with Applications to Clinical Trials surveys and extends current methods for planning and conducting interim analyses. It describes group sequential stopping rules which can reduce average study length while controlling error probabilities. Procedures are presented in a manner which allows their easy implementation to the wide variety of data types arising from clinical trials." "Group Sequential Methods with Applications to Clinical Trials is an invaluable aid for medical statisticians in the pharmaceutical industry, medical research institutes and hospitals, as well as academic statisticians in biostatistics and epidemiology.
