The Effect Of Omitted Spatial Effects And Social Dependence In The Modelling Of Household Expenditure For Fruits And Vegetables [PDF]
, 2014 We find the omitted elements of the external environment affect negatively the estimates for other spatial (social) effect parameters. Especially, we notice the overestimation of the random effect variance when the social dependence is omitted and the ...

Predicting the size and probability of epidemics in a population with heterogeneous infectiousness and susceptibility [PDF]
, 2007 We analytically address disease outbreaks in large, random networks with heterogeneous infectivity and susceptibility. The transmissibility $T_{uv}$ (the probability that infection of $u$ causes infection of $v$) depends on the infectivity of $u$ and the

Selection for uniformity in livestock by exploiting genetic heterogeneity of residual variance
Genetics Selection Evolution, 2008 In some situations, it is worthwhile to change not only the mean, but also the variability of traits by selection. Genetic variation in residual variance may be utilised to improve uniformity in livestock populations by selection.

Using Bayes weights to remedy the heterogeneity problem of random error variance in linear models [PDF]
المجلة العراقية للعلوم الاحصائية, 2020 In this research, it was suggested to use the InformativeBayes method in calculating the Bayes weights and use them to treat the of heterogeneity problem when estimating the linear regression model parameters using the weighted least squares method ...

A study of heterogeneity of environmental variance for slaughter weight in pigs
Animal, 2008 This work presents an analysis of heterogeneity of environmental variance for slaughter weight (175 days) in pigs. This heterogeneity is associated with systematic and additive genetic effects.

Inheritance beyond plain heritability: variance-controlling genes in Arabidopsis thaliana. [PDF]
PLoS Genetics, 2012 The phenotypic effect of a gene is normally described by the mean-difference between alternative genotypes. A gene may, however, also influence the phenotype by causing a difference in variance between genotypes.

Evaluating gene by sex and age interactions on cardiovascular risk factors in Brazilian families
BMC Medical Genetics, 2010 Background In family studies, it is important to evaluate the impact of genes and environmental factors on traits of interest. In particular, the relative influences of both genes and the environment may vary in different strata of the population of ...

Diet standardization reduces intra-individual microbiome variation
Gut Microbes, 2022 The human gut microbiota is highly heterogenous between individuals and also exhibits considerable day-to-day variation within individuals. We hypothesized that diet contributed to such inter- and/or intra-individual variance.
