Article convidat de la revista SORT: Independent increments in group sequential tests: a review

La revista SORT (Statistics and Operations Research Transactions) es complau a convidar-vos a la presentació de l’article  “Independent increments in group sequential tests: a review” La presentació serà a càrrec de KyungMann Kim, professor de l’School of Medicine and Public Health, de la Universitat de Wisconsin-Madison. Resum de l’article: In order to apply group sequential methods for interim analysis for early stopping in clinical trials, the joint distribution of test statistics over time has to be known. Often the distribution is multivariate normal or asymptotically so, and an application of group sequential methods requires multivariate integration to determine the group sequential boundaries. However, if the increments between successive test statistics are independent, the multivariate integration reduces […]
