On Matrix Sampling and Imputation of Context Questionnaires With Implications for the Generation of Plausible Values in Large-Scale Assessments

David Kaplan, Dan Su
2016 Journal of educational and behavioral statistics  
Study 3 examines imputation and plausible values generation within a partially balanced incomplete block design.  ...  1 uses data from PISA 2012 to examine several different forms of missing data imputation within the chained equations framework: predictive mean matching, Bayesian linear regression, and proportional odds  ...  However, here we arrange the 19 scales according to a partially balanced incomplete block design with three associate classes (Montgomery, 2012) .  ...

Integration of balance and strength training into daily life activity to reduce rate of falls in older people (the LiFE study): randomised parallel trial

L. Clemson, M. A. Fiatarone Singh, A. Bundy, R. G. Cumming, K. Manollaras, P. O'Loughlin, D. Black
2012 The BMJ (British Medical Journal)  
LiFE and structured groups received five sessions with two booster visits and two phone calls; controls received three home visits and six phone calls.  ...  LiFE and structured groups had a significant and moderate improvement in dynamic balance, compared with controls.  ...  LiFE participants significantly improved compared with controls, with moderate to large effect sizes for the two balance hierarchy scales.  ...

Combinatorial designs

Douglas R. Stinson
2008 ACM SIGACT News  
We will spend quite a bit of time in this chapter looking at pairwise balanced designs with specified block sizes.  ...  This means that (X, A) has at least v + blocks, and the proof is complete. A pairwise balanced design with one block size is a BIBD.  ...  In Table A then apply block complementation, which was presented as Theorem 1.32, and/or Exercise 3.1).  ...

Circular designs balanced for neighbours at distances one and two

R. E. L. Aldred, R. A. Bailey, B. D. Mckay, I. M. Wanless
2014 Biometrika  
The designs are balanced with respect to neighbours at distance one and at distance two.  ...  We define three types of neighbour-balanced designs for experiments where the units are arranged in a circle or single line in space or time.  ...  For a design with nk inner plots, a necessary condition is the existence of a balanced incomplete-block design for n treatments in n blocks of size k.  ...

Some Pairwise Balanced Designs

Malcolm Greig
1999 Electronic Journal of Combinatorics  
A pairwise balanced design, $B(K;v)$, is a block design on $v$ points, with block sizes taken from $K$, and with every pair of points occurring in a unique block; for a fixed $K$, $B(K)$ is the set of  ...  We construct a 78 element basis for $N_{1(8)}$ with, at most, 64 inessential elements. 3.  ...  The problem of Section 8 was one of the first combinatorial problems I tackled, and in these last ten years, I have had discussions and preprints which have helped me with the problems in this paper, and  ...

Analysis of local genome rearrangement improves resolution of ancestral genomic maps in plants

Diego P. Rubert, Fábio V. Martinez, Jens Stoye, Daniel Doerr
2020 BMC Genomics  
With the enhanced workflow at hand, we reconstruct the ancestral genome of eudicots, a major sub-clade of flowering plants, using whole genome sequences of five modern plants.  ...  Our reconstructed genome is highly detailed, yet its layout agrees well with that reported in Badouin et al. (2017).  ...  We limited then the number of overlapping syntenic blocks to 30 and chose (heuristically) promising subsets whenever this limit was exceeded.  ...

Cube-tilings of ℝ n and nonlinear codesand nonlinear codes

J. C. Lagarias, P. W. Shor
1994 Discrete & Computational Geometry  
Coding theory is concerned with the construction of such sets whose vectors are far apart in an appropriate metric, and which correspond to dense packings of space with appropriately scaled unit balls  ...  We construct cube-tilings of R" such that no two cubes have a common face of dimension exceeding n -~x/~. J.c. Lagarias and P. W. Shor over in a simple manner from one dimension to another.  ...  We always have, for i = Jx within a block, for all i 9 R such that 1 < i < n, completing (a).

COBALT: constraint-based alignment tool for multiple protein sequences

J. S. Papadopoulos, R. Agarwala
2007 Bioinformatics  
COBALT finds a collection of pairwise constraints derived from database searches, sequence similarity and user input, combines these pairwise constraints, and then incorporates them into a progressive  ...  We also show that COBALT has reasonable runtime performance and alignment accuracy comparable to or exceeding that of other tools for a broad range of problems.  ...  We thank Aravind Iyer for testing COBALT with his datasets and providing valuable feedback.  ...
