Biased coin design with imbalance tolerance

Communications in Statistics. Stochastic Models, 1999
Summary: One of the main aspects of a sampling procedure is to determine how to collect samples. A completely random sampling scheme is free of any bias and provides a basis for valid statistical inferences. A balanced sampling scheme strengthens efficiency in statistical inference procedures.

Bayesian Adaptive Biased‐Coin Designs for Clinical Trials with Normal Responses

Biometrics, 2005
Summary Adaptive designs are used in phase III clinical trials for skewing the allocation pattern toward the better treatments. We use optimum design theory to derive a skewed Bayesian biased‐coin procedure for sequential designs with continuous responses.

Doubly adaptive biased coin designs with delayed responses

Canadian Journal of Statistics, 2008
AbstractIn clinical studies, patients are usually accrued sequentially. Response‐adaptive designs are then useful tools for assigning treatments to incoming patients as a function of the treatment responses observed thus far. In this regard, doubly adaptive biased coin designs have advantageous properties under the assumption that their responses can ...

The Accelerated Biased Coin Up-and-Down Design in Phase I Trials

Journal of Biopharmaceutical Statistics, 2004
The biased coin up-and-down design (BCD) is used to allocate doses in phase I clinical trials. The BCD requires that the treatment response or the toxicity evaluation is observed quickly. In trials with a long treatment evaluation, the BCD will lead to long trial duration because a new patient cannot be enrolled until the preceding patient has ...
