Variance component analysis of skin and weight data for sheep subjected to rapid inbreeding [PDF]

, 1999
A variance component analysis was carried out on data from a 20-year experiment in the rapid inbreeding of purebred and crossbred lines of three hill breeds of sheep.

Relative Performance of Components Variance Estimators in Random Effects Models [PDF]

فصلنامه پژوهش‌های اقتصادی ایران, 2012
This paper presents an assessment of the small-sample performance of the three well-known estimators of components variance in random effects model for panel data. The estimators considered are Swamy-Arora, Wansbeek-Kaptayn and Wallace-Hussain.

Dissecting total genetic variance into additive and dominance components of purebred and crossbred pig traits

Animal, 2019
The partition of the total genetic variance into its additive and non-additive components can differ from trait to trait, and between purebred and crossbred populations.

Linear model with inaccurate variance components [PDF]

, 1996
summary:A linear model with approximate variance components is considered. Differences among approximate and actual values of variance components influence the proper position and the shape of confidence ellipsoids, the level of statistical tests and ...

Prediction of a Small Area Mean for an Infinite Population when the Variance Components Are Random [PDF]

In this paper, we propose a new model with random variance components for estimating small area characteristics. Under the proposed model, we derive the empirical best linear unbiased estimator, an approximation to terms of order and an estimator whose ...

Semi-Arid Environmental Conditions and Agronomic Traits Impact on the Grain Quality of Diverse Maize Genotypes

Plants
We assessed the impact of environmental conditions and agronomic traits on maize grain quality parameters. The study was conducted using genotypes with distinct genetic constitutions developed specifically for late sowing in semi-arid environments.
