Randomization by minimization for unbalanced treatment allocation
Statistics in Medicine, 2009AbstractMinimization is a dynamic randomization technique that has been widely used in clinical trials for achieving a balance of prognostic factors across treatment groups, but most often it has been used in the setting of equal treatment allocations.

BMJ, 2013
Researchers investigated the effects of manual lymph drainage on the development of lymphoedema related to breast cancer. A randomised single blinded controlled trial was performed. The intervention was a six months’ treatment programme consisting of guidelines about prevention of lymphoedema, exercise therapy, and manual lymph drainage.

Additive Decompositions, Random Allocations, and Threshold Phenomena
Combinatorics, Probability and Computing, 2004An additive decomposition of a set $I$ of nonnegative integers is an expression of $I$ as the arithmetic sum of two other such sets. If the smaller of these has $p$ elements, we have a $p$-decomposition. If $I$ is obtained by randomly removing $n^{\alpha}$ integers from $\{0,\dots,n-1\}$, decomposability translates into a balls-and-urns problem, which ...

Adaptive allocation in randomized controlled trials
Controlled Clinical Trials, 1985Adaptive allocation has been proposed as a procedure to reduce the risk of chance imbalance of important prognostic factors in randomized controlled trials when the number of prognostic factors is large. In this article, minimization, a type of adaptive allocation, is compared to simple randomization and stratified allocation in a series of Monte Carlo

The Complexity of Computing the Random Priority Allocation Matrix
Mathematics of Operations Research, 2013The random priority (RP) mechanism is a popular way to allocate n objects to n agents with strict ordinal preferences over the objects. In the RP mechanism, an ordering over the agents is selected uniformly at random; the first agent is then allocated his most-preferred object, the second agent is allocated his most-preferred object among the ...

The Random Allocation of Patients in Clinical Trials
Methods of Information in Medicine, 1966The allocation of patients in controlled clinical trials may be by random selection or by a system of stratification. True matching of the two series can, however, only be achieved by a system of pairing of patients. Such a system is described.

The Home Office and Random Allocation Experiments
Evaluation Review, 2003By examining the history of the random experiment in the Home Office in the United Kingdom, this article demonstrates that research is not an altogether rational process and that fashion, personality, and politics are at least as important as science and evidence when setting research and policy programs and determining methodologies.
