Immigrated urn models - asymptotic properties and applications
Li-Xin Zhang, Feifang Hu, Siu Hung Cheung +1
Urn models have been widely studied and applied in both scientific and social science disciplines. In clinical studies, the adoption of urn models in treatment allocation schemes h…
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…
Asymptotic theorems of sequential estimation-adjusted urn models
Li-X. Zhang, Feifang Hu, Siu Hung Cheung
The Generalized Pólya Urn (GPU) is a popular urn model which is widely used in many disciplines. In particular, it is extensively used in treatment allocation schemes in clinical t…
