Open Source Web Based Software for Random Assignment/Allocation Methods in Data Processing

2019 International Artificial Intelligence and Data Processing Symposium (IDAP), 2019
In this study, it is aimed to develop a user-friendly open-source web-based software which enables the assignment of the subjects included in the scientific research to the groups with equal probability.

Stratified random allocation

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, 2004
An 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 ...

Randomization. Part 3: Allocation concealment and randomization implementation

American Journal of Orthodontics and Dentofacial Orthopedics, 2012
Randomization consists of 3 steps: generation of the random allocation sequence, allocation concealment, and implementation of the random allocation sequence. In the previous 2 articles, we discussed the methods to generate the random allocation sequence (the Table summarizes these methods); in this final article on randomization, we will discuss ...

Using Random Allocation to Evaluate Social Interventions: Three Recent U.K. Examples

, 2003
Although widely accepted in medicine and health services research, randomized controlled trials (RCTs) are often viewed with hostility by social scientists, who cite a variety of reasons as to why this approach to evaluation cannot be used to research ...

Adaptive allocation in randomized controlled trials

Controlled Clinical Trials, 1985
Adaptive 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

Randomization by minimization for unbalanced treatment allocation

Statistics in Medicine, 2009
AbstractMinimization 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.

Fuzzy Random Redundancy Allocation Problems

2010
Due to subjective judgement, imprecise human knowledge and perception in capturing statistical data, the real data of lifetimes in many systems are both random and fuzzy in nature. Based on the fuzzy random variables that are used to characterize the lifetimes, this paper studies the redundancy allocation problems to a fuzzy random parallel-series ...
