Randomization in clinical studies [PDF]
Korean Journal of Anesthesiology, 2019 Randomized controlled trial is widely accepted as the best design for evaluating the efficacy of a new treatment because of the advantages of randomization (random allocation).

Mathematics, 2022 We consider the usual random allocation model of distinguishable particles into distinct cells in the case when there are an even number of particles in each cell. For inhomogeneous allocations, we study the numbers of particles in the first K cells.

Optimal allocation of sample size for randomization-based inference from $2^K$ factorial designs [PDF]
Journal of Causal Inference 12, no. 1 (2024), 2023 Optimizing the allocation of units into treatment groups can help researchers improve the precision of causal estimators and decrease costs when running factorial experiments. However, existing optimal allocation results typically assume a super-population model and that the outcome data comes from a known family of distributions.

Indian Journal of Dental Research, 2023 Background: In randomised controlled trials (RCTs), the application of a test of significance to compare the baseline differences between the intervention groups is a common practice, though it has been condemned by many researchers.

Journal of Medical Radiation Sciences, 2023 Introduction The aim of this study was to comparatively evaluate the learning outcomes achieved by first‐year radiography students educated with either virtual reality (VR) simulation training or physical simulation training. The implementation of VR has

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

Approximate Random Allocation Mechanisms [PDF]
The 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.

Energies, 2017 With the incremental introduction of solar photovoltaic (PV) generators into existing power systems, and their fast-growing share in the gross electricity generation, system voltage stability has become a critical issue.

Sensors, 2020 In this letter, we investigate the idea of interference spreading and its effect on bit error rate (BER) performance in a cognitive radio network (CRN). The interference spreading phenomenon is caused because of the random allocation of subcarriers in an
