Item Selection With Biased-Coin Up-and-Down Designs [PDF]
, 2020 Targeting any arbitrary percentile, the biased-coin up-and-down design is theoretically appealing and can provide an efficient alternative to the current maximum Fisher information method for item selection in adaptive testing. This paper illustrates the

A Sequential Probability Ratio Test Using a Biased Coin Design
The Annals of Statistics, 1985 Consider a sequential probability ratio test comparing two treatments, where each subject receives only one of the treatments. Each subject's treatment assignment is determined by the flip of a biased coin, where the bias serves to balance the number of patients assigned to each treatment.

Generalized Efron's biased coin design and its theoretical properties
Journal of Applied Probability, 2016 AbstractIn clinical trials with two treatment arms, Efron's biased coin design, Efron (1971), sequentially assigns a patient to the underrepresented arm with probabilityp> ½. Under this design the proportion of patients in any arm converges to ½, and the convergence rate isn-1, as opposed ton-½under some other popular designs.

Biased coin designs: some properties and applications
, 1995 A brief review of biased coin designs is presented. Some asymptotic properties of the adaptive biased coin designs of Wei (1978) and Eisele (1994) are given. Applications of biased coin designs to estimation and testing problems are also given.

The minimum effective concentration (MEC90) of bupivacaine for an ultrasound-guided suprainguinal fascia iliaca compartment block for analgesia in knee surgery: a dose-finding study [PDF]
Korean Journal of AnesthesiologyBackground In recent years, the suprainguinal fascia iliaca compartment block (SFICB) has become more common in clinical practice. This assessor-blinded dose-finding study aimed to determine the minimum effective concentration (MEC90, MEC95) of ...

The Annals of Statistics, 2012 The present paper deals with the problem of allocating patients to two competing treatments in the presence of covariates or prognostic factors in order to achieve a good trade-off among ethical concerns, inferential precision and randomness in the treatment allocations.
