Asymptotics in response-adaptive designs generated by a two-color, randomly reinforced urn
双色随机强化 urn 生成的反应自适应设计:渐近性质
This paper illustrates asymptotic properties for a response-adaptive design generated by a two-color, randomly reinforced urn model. The design considered is optimal in the sense that it assigns patients to the best treatment, with probability converging to one. An approach to show the joint asymptotic normality of the estimators of the mean responses to the treatments is provided in spite of the fact that allocation proportions converge to zero and one. Results on the rate…
