Asymptotics in randomized urn models

Zhidong Bai, +1 more
TL;DR: In this article, the authors studied a very general urn model stimulated by designs in clinical trials, where the number of balls of different types added to the urn at trial n depends on a random outcome directed by the composition at trials 1,2,…,n−1.

Asymptotic properties of adaptive designs for clinical trials with delayed response

TL;DR: In this article, the authors derived the limiting distribution of the urn composition under staggered entry and delayed response for adaptive clinical trials using a generalized Friedman's urn design, and showed that maximum likelihood estimators from such a trial have the usual asymptotic properties.

Group-Sequential Response-Adaptive Designs for Comparing Several Treatments

Wenyu Liu
TL;DR: The adaptive design generalised to multi-arm clinical trials is studied and the application of the adaptive design to censored survival responses is investigated and different optimal response-adaptive randomised procedures compared.

Some aspects of the sequential design of experiments

TL;DR: The authors proposed a theory of sequential design of experiments, in which the size and composition of the samples are not fixed in advance but are functions of the observations themselves, which is a major advance.

Group Sequential Methods with Applications to Clinical Trials

TL;DR: A short history of sequential and group sequential methods can be found in this paper, where the authors present a road map for the application of two-sided tests for comparing two treatments with normal response of known variance.

Forcing a sequential experiment to be balanced

TL;DR: In this paper, a new method of assigning the subjects which tends to balance the experiment, but at the same time is not over vulnerable to various common forms of experimental bias is discussed.

Extracorporeal circulation in neonatal respiratory failure: a prospective randomized study.

TL;DR: In this paper, a prospective controlled randomized study of the use of extracorporeal membrane oxygenation to treat newborns with respiratory failure was carried out using the randomized play-the-winner statistical method, where the chance of randomly assigning an infant to one treatment or the other is influenced by the outcome of treatment of each patient in the study.
