Group Sequential Clinical Trials: A Classical Evaluation of Bayesian Decision-Theoretic Designs
组序贯临床试验:贝叶斯决策论设计的经典统计评价
Bayesian decision-theoretic designs for a clinical trial comparing two treatments for a disease with binary outcomes are developed and evaluated. The probability of successful outcome with treatment i is denoted by pi , i = 1, 2, and prior knowledge regarding each pi is assumed to follow a beta distribution. The pi are assumed to be independent. To facilitate comparison with frequentist clinical trial designs, we take a hypothesis-testing approach. The null hypothesis is δ <…
