How to do random allocation (randomization). [PDF]

open access: yesClin Orthop Surg, 2014
To explain the concept and procedure of random allocation as used in a randomized controlled study.We explain the general concept of random allocation and demonstrate how to perform the procedure easily and how to report it in a paper.

Approximate Random Allocation Mechanisms [PDF]

open access: yesThe Review of Economic Studies, 2014
Abstract We generalize the scope of random allocation mechanisms, in which the mechanism first identifies a feasible “expected allocation” and then implements it by randomizing over nearby feasible integer allocations. The previous literature has shown that the cases in which this is possible are sharply limited.

Random allocation software for parallel group randomized trials [PDF]

open access: yesBMC Medical Research Methodology, 2004
Abstract Background Typically, randomization software should allow users to exert control over the different aspects of randomization including block design, provision of unique identifiers and control over the format and type of program output.

Random-allocation and urn models

open access: yesJournal of Applied Probability, 2004
We review some urn and random-allocation models, mostly using probability generating function (PGF) methods. We begin by formulating a basic problem which can be thought of as either an urn or a random-allocation model; a PGF solution to it is outlined.

Random allocation or allocation at random? Patients' perspectives of participation in a randomised controlled trial [PDF]

open access: yesBMJ, 1998
To explore trial participants' understandings of randomisation.In this exploratory study, which used qualitative research methods, in-depth, semistructured interviews were carried out with 20 participants from the CLasP randomised controlled trial. Interviews were recorded on audio tape and fully transcribed. Data were analysed by comparing transcripts

Pricing Randomized Allocations

open access: yesProceedings of the Twenty-First Annual ACM-SIAM Symposium on Discrete Algorithms, 2010
Randomized mechanisms, which map a set of bids to a probability distribution over outcomes rather than a single outcome, are an important but ill-understood area of computational mechanism design. We investigate the role of randomized outcomes (henceforth, "lotteries") in the context of a fundamental and archetypical multi-parameter mechanism design ...

Balanced allocation through random walk [PDF]

open access: yesInformation Processing Letters, 2018
We consider the allocation problem in which $m \leq (1- ) dn $ items are to be allocated to $n$ bins with capacity $d$. The items $x_1,x_2,\ldots,x_m$ arrive sequentially and when item $x_i$ arrives it is given two possible bin locations $p_i=h_1(x_i),q_i=h_2(x_i)$ via hash functions $h_1,h_2$.

On the efficiency and optimality of random allocations

open access: yesJournal of Mathematical Analysis and Applications, 1985
AbstractAllocations in a random economy described by an integrably bounded, closed and convex valued, measurable consumption multifunction and a monotone, continuous utility function are studied. The notions of efficiency and optimality of allocations are introduced and compared.

A Limit Theorem for Random Allocations

open access: yesJournal of Mathematics Research, 2012
A limit theorem is presented for random allocations. For a fixed period we allocate $m$ balls into $N$ boxes. We repeat the experiment throughout $n$ periods. Let $p_q$ denote the probability that we do not place more than $q$ balls  into any of the $N$ boxes during any of the $n$ repetitions. The limit of $p_q$ is determined when $m,n,N \to \infty$.
