摘要
A biased coin design is proposed for the allocation of subjects to treatments A and B in a clinical trial when the desired allocation proportions are unknown. The design is doubly adaptive in the sense that it takes account of the proportion of subjects assigned to each treatment and the current estimate of the desired allocation proportion. A strong law of large numbers is established for the proportion of subjects assigned to a treatment when subject responses are independent random variables from standard exponential families. The normal case is presented as an application.
