Method and Effect of Adjustment for Heterogeneous Variance
Journal of Dairy Science, 1991 Lactation records were standardized for differing genetic and error variances across herds and over time based on phenotypic variance for each herd-year-parity group. Each herd-year-parity phenotypic variance estimate was combined with those of adjacent years and regressed toward a region-year-parity variance. Heritability was assumed to be .25 at mean

Texture analysis of vertebral bone marrow using chemical shift encoding–based water-fat MRI:a feasibility study [PDF]
, 2019 Summary This feasibility study investigated the spatial heterogeneity of the lumbar vertebral bone marrow using chemical shift encoding–based water-fat MRI. Acquired texture features like contrast and dissimilarity allowed for differentiation of pre- and

Accounting for Local Geological Variability in Sequential Simulations—Concept and Application
ISPRS International Journal of Geo-Information, 2020 Heterogeneity-preserving property models of subsurface regions are commonly constructed by means of sequential simulations. Sequential Gaussian simulation (SGS) and direct sequential simulation (DSS) draw values from a local probability density function ...

Genetic dissection of the Drosophila melanogaster female head transcriptome reveals widespread allelic heterogeneity. [PDF]
PLoS Genetics, 2014 Modern genetic mapping is plagued by the "missing heritability" problem, which refers to the discordance between the estimated heritabilities of quantitative traits and the variance accounted for by mapped causative variants.

Model-specific tests on variance heterogeneity for detection of potentially interacting genetic loci
BMC Genetics, 2012 Background Trait variances among genotype groups at a locus are expected to differ in the presence of an interaction between this locus and another locus or environment.

Psychosocial Outcomes in Patients With Endocrine Tumor Syndromes: A Systematic Review
Pediatric Blood &Cancer, EarlyView.ABSTRACT Introduction The combination of disease manifestations, the familial burden, and varying penetrance of endocrine tumor syndromes (ETSs) is unique. This review aimed to portray and summarize available data on psychosocial outcomes in patients with ETSs and explore gaps and opportunities for future research and care.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Ongoing evidence indicates increased risk of sarcopenic obesity among children and young people (CYP) with acute lymphoblastic leukemia (ALL), often beginning early in treatment, persisting into survivorship. This review evaluates current literature on body composition in CYP with ALL during and after treatment.

BMC Medical Research Methodology, 2013 Background Multiple treatment comparison (MTC) meta-analyses are commonly modeled in a Bayesian framework, and weakly informative priors are typically preferred to mirror familiar data driven frequentist approaches.

A comparison of heterogeneity variance estimators in simulated random‐effects meta‐analyses
Research Synthesis Methods, 2018 Studies combined in a meta‐analysis often have differences in their design and conduct that can lead to heterogeneous results. A random‐effects model accounts for these differences in the underlying study effects, which includes a heterogeneity variance ...
