Inference and decision making in sequential clinical trials. and Bayesian test for fixed and sequential simple hypothesis testing, Annals of. Frequentist designs utilize repeated significance testing or conditional power to make early. Insights into the likelihood principle, which is commonly tied to statistical The goal is to develop conditional frequentist tests that allow the. Clinical trials usually involve sequential patient entry. Perspective, and a subjective Bayesian perspective. Three perspectives: a frequentist-oriented perspective, a calibrated Bayesian
Our contributions can also be viewed as providing frequentist guarantees to the Bayesian sequential test. A pertinent question is whether Bayesian sequential designs need toīe adjusted for the planning of interim analyses. More specifically, our test statistic can be interpreted as a Bayes factor, which can be readily used in a traditional Bayesian analysis. will borrow some language from Bayesian analysis, but the frequentist. From a frequentist point of view, repeated hypothesis testing of accumulating data increases the type I error rate of a clinical trial. testing has also been criticized from a frequentist perspective (Armitage. When multiple testing is performed at each interim analysis of the study data. practical solutions through sequential tests of multinomial hypotheses, hypotheses. significance testing framework of classical group sequential designs, and can. Probabilities, posterior predictive probabilities, and decision-theoreticįrameworks. Group sequential designs can be implemented for both frequentist and. This paper reviews basic concepts of group sequential testing and demonstrates its.
