Asymptotic Properties of Random Restricted Partitions
Mathematics, 2023 We study two types of probability measures on the set of integer partitions of n with at most m parts. The first one chooses the partition with a chance related to its largest part only. We obtain the limiting distributions of all of the parts together and that of the largest part as n tending to infinity for m fixed or tending to infinity with m=o(n1 ...

Randomized benchmarking with restricted gate sets [PDF]
Physical Review A, 2018 Standard randomized benchmarking protocols entail sampling from a unitary 2 design, which is not always practical. In this article we examine randomized benchmarking protocols based on subgroups of the Clifford group that are not unitary 2 designs. We introduce a general method for analyzing such protocols and subsequently apply it to two subgroups ...

Restricted Isometry Property of Random Subdictionaries [PDF]
IEEE Transactions on Information Theory, 2015 We study statistical restricted isometry, a property closely related to sparse signal recovery, of deterministic sensing matrices of size $m \times N$. A matrix is said to have a statistical restricted isometry property (StRIP) of order $k$ if most submatrices with $k$ columns define a near-isometric map of ${\mathbb R}^k$ into ${\mathbb R}^m$.

Exact properties of Efron's biased coin randomization procedure [PDF]
, 2010 Efron [Biometrika 58 (1971) 403--417] developed a restricted randomization procedure to promote balance between two treatment groups in a sequential clinical trial. He called this the biased coin design. He also introduced the concept of accidental bias,

randomizeR: An R Package for the Assessment and Implementation of Randomization in Clinical Trials
Journal of Statistical Software, 2018 Randomization in clinical trials is the key design technique to ensure the comparability of treatment groups. Although there exist a large number of software products which assist the researcher to implement randomization, no tool which would cover a ...

Allocation techniques for balance at baseline in cluster randomized trials: a methodological review
Trials, 2012 Reviews have repeatedly noted important methodological issues in the conduct and reporting of cluster randomized controlled trials (C-RCTs). These reviews usually focus on whether the intracluster correlation was explicitly considered in the design and ...

The Influence of Matrix Size on Statistical Properties of Co-Occurrence and Limiting Similarity Null Models. [PDF]
PLoS ONE, 2016 Null models exploring species co-occurrence and trait-based limiting similarity are increasingly used to explore the influence of competition on community assembly; however, assessments of common models have not thoroughly explored the influence of ...
