Genetic parameters for some growth traits of Nigerian local chickens [PDF]

open access: yesBiotechnology in Animal Husbandry, 2017
Genetic parameters were estimated for bodyweight (BWT), shank length (SHL), and wing length (WL) of Nigerian local chicken (NLC) from 4 to 20 weeks of age by fitting dyadic mixed model (dmm) equations which yield estimates of variance components ...

An investigation into the correlations among GNSS observations and their impact on height and zenith wet delay estimation for medium and long baselines [PDF]

open access: yes, 2012
Most stochastic modelling techniques neglect the correlations among the raw un-differenced observations when forming the variance–covariance matrix of the Global Navigation Satellite System (GNSS) observations.

A comparison between Bayes estimation and the estimation of the minimal unbiased quadratic Standard of the bi-division variance analysis model in the presence of interaction

open access: yesTikrit Journal of Pure Science, 2020
In this study, the variance compounds parameters of the mixed bi-division variance analysis sample are estimated. This estimation is obtained, by Bayes quadratic unbiased estimator. The second way to estimate variance compounds parameters of a suggested

Genetic Effect on Amylose and Protein Contents in the Crossed Rice Seeds

open access: yesPlant Production Science, 2002
The nature of gene action may be revealed and desirable parents may be found by analyzing the combining ability and estimating the degree of heterosis in an early generation. Currently, varieties with a good eating quality are preferred.

Estimation of variance components in mixed linear models [PDF]

open access: yes, 1992
summary:The MINQUE of the linear function $\int'\vartheta$ of the unknown variance-components parameter $\vartheta$ in mixed linear model under linear restrictions of the type $\bold R\vartheta = c$ is defined and derived.

Les modèles d'analyse de la variance à un ou deux facteurs avec effets aléatoires : MINQUE = ANOVA

open access: yes, 1995
l'objet de cet article est l'étude des modèles d'analyse de la variance à au plus deux facteurs à effets aléatoires pour des plans équilibrés. Plus particulièrement, nous nous intéressons à l'estimation des composantes de la variance.

On the principle of MINQUE for the estimation of variance and covariance components [PDF]

open access: yes, 2000
In this thesis, we describe the method of MINQUE (C. R. Rao (1970)) and its various generalizations (C. R. Rao (1971, 1972), Chaubey (1977), P. S. R. S. Rao and Chaubey (1978)). This method can be used if some information about the variance components is

Comparison of two-level hlm estimators via mc simulations: reml vs minque.

open access: yes, 2016
The purpose of the study was to compare the performance of two estimation procedures, REML and MINQUE, for a two-level hierarchical linear model. It was expected that the variance-covariance components estimates provided by MINQUE procedure will have ...
