Efficient randomized-adaptive designs
Feifang Hu, Li-Xin Zhang, Xuming He
Response-adaptive randomization has recently attracted a lot of attention in the literature. In this paper, we propose a new and simple family of response-adaptive randomization pr…
Adaptive Allocation Theory in Clinical Trials
Li-Xin Zhang
Various adaptive randomization procedures (adaptive designs) have been proposed to clinical trials. This paper discusses several broad families of procedures, such as the play-the-…
On the rates of the other law of the logarithm
Li-Xin Zhang
By using the strong approximation, this paper establishes several limit results on the convergent rate of a infinite series of probabilities on the other law of iterated logarithm.
Precise Asymptotics in Chung's law of the iterated logarithm
Li-Xin Zhang
This paper gives sufficent and necessary conditions on a kind of limit results to hold on the precise convergent rate of an infinite series of probabilities on the Chung type law o…
Precise rates in the law of the iterated logarithm
Li-Xin Zhang
Let , , , be i.i.d. random variables, and let be the partial sums and be the maximum partial sums. We give the suffi…
Asymptotic Properties of Covariate-Adjusted Adaptive Designs
Li-Xin Zhang, Feifang Hu, Siu Hung Cheung +1
Response-adaptive designs have been extensively studied and used in clinical trials. However, there is a lack of a comprehensive study of response-adaptive designs that include cov…
