Maximum Lilkelihood and Restricted Maximum Likelihood Estimation for a Class of Gaussian Markov Random Fields [PDF]

This work describes a Gaussian Markov random field model that includes several previously proposed models, and studies properties of their maximum likelihood (ML) and restricted maximum likelihood (REML) estimators in a special case.

Sea-surface pCO2 maps for the Bay of Bengal based on advanced machine learning algorithms

Scientific Data
Lack of sufficient observations has been an impediment for understanding the spatial and temporal variability of sea-surface pCO2 for the Bay of Bengal (BoB).

Selection of sugarcane families and parents by Reml/Blup

Cropp Breeding and Applied Biotechnology, 2005
Were evaluated 113 full-sib families obtained by unbalanced diallel matings in three experiments in an augmented block design (ABD) planted side by side in the same area. The individual and joint analyses of the experiments were performed by the Reml/Blup method.

Fitting Linear Mixed-Effects Models Using lme4

Journal of Statistical Software, 2015
Maximum likelihood or restricted maximum likelihood (REML) estimates of the parameters in linear mixed-effects models can be determined using the lmer function in the lme4 package for R. As for most model-fitting functions in R, the model is described in

Genetic parameters and genetic and phenotypic trends of performance traits of equines from the Brazilian Army

Revista Brasileira de Zootecnia, 2012
The objective of this research was to compare the magnitude of genetic parameters (coefficients of heritability and genetic correlation) as estimated by the Restricted Maximum Likelihood (REML) method and Bayesian Inference, and to estimate the genetic ...

Out of Sample Estimation for Small Areas using Area Level Data

, 2005
A Fay-Herriot type model with independent area effects is often assumed when small area estimates based on area level data are required. However, under this approach out of sample areas are limited to synthetic estimates.

Estimadores de componentes de variância em delineamento de blocos aumentados com tratamentos novos de uma ou mais populações Estimators of variance components in the augmented block design with new treatments from one or more populations

Pesquisa Agropecuária Brasileira, 2001
O objetivo do trabalho foi comparar, por meio de simulação, as estimativas de componentes de variância produzidas pelos métodos ANOVA (análise da variância), ML (máxima verossimilhança), REML (máxima verossimilhança restrita) e MIVQUE(0) (estimador ...

Selection of umbu-cajazeira clones using the REML/BLUP

Revista Brasileira de Ciências Agrárias - Brazilian Journal of Agricultural Sciences, 2017
Genetic parameters and genotypic values of fruits from umbu-cajazeira clones were determined using the restricted maximum likelihood/best linear unbiased prediction (REML/BLUP) method, from the morphological, physicochemical and chemical characterization of fruits.
