Copula miss-specification in REML multivariate genetic animal model estimation

open access: yesGenetics Selection Evolution, 2022
Background In animal genetics, linear mixed models are used to deal with genetic and environmental effects. The variance and covariance terms of these models are usually estimated by restricted maximum likelihood (REML), which provides unbiased ...

Addressing spatial variability in provenance experiments exemplified in two trials with black spruce

open access: yesJournal of Forest Science, 2007
Two exemplary black spruce (Picea mariana [Mill.] B.S.P.) provenance trials were analyzed using traditional and spatial techniques. The objective was to find out possible differences between these approaches in terms of both the resulting fit-statistics ...

Professor Endrenyi’s Legacy: An Evaluation of the Regulatory Requirement “Fixed Effects, Rather Than Random Effects, Should Be Used for All Terms”

open access: yesJournal of Pharmacy & Pharmaceutical Sciences, 2021
Purpose: In the latest revision of the guideline for evaluation of bioequivalence (BE), European regulators introduced the requirement for using subjects as fixed factors in the underlying statistical models, even in replicate and semi-replicate studies.

Binary and Ordinal Random Effects Models Including Variable Selection [PDF]

open access: yes, 2010
A likelihood-based boosting approach for fitting binary and ordinal mixed models is presented. In contrast to common procedures it can be used in high-dimensional settings where a large number of potentially influential explanatory variables is available.

An Information Integration Strategy based on REML [PDF]

open access: yesAdvances in Engineering Research, 2015
The paper introduces a strategy "Integration of heterogeneous information in the Distributed System based on REML". In the strategy, we wrap different formats, distributed heterogeneous information into the unified REML information, and make it to be re-utilized by Web Service which is a method of communication between some electronic devices or ...

Exact and approximate REML for heteroscedastic regression [PDF]

open access: yesStatistical Modelling, 2001
Exact REML for heteroscedastic linear models is compared with a number of approximate REML methods which have been proposed in the literature, especially with the methods proposed by Lee and Nelder (LN98) and Smyth and Verbyla (SV99) for simultaneous mean-dispersion modelling in generalized linear models.

Seleção de clones de batata-doce pelo procedimento REML/BLUP = Sweet potato clone selection by REML/BLUP procedure

open access: yesActa Scientiarum: Agronomy, 2010
Objetivou-se classificar e selecionar clones de batata-doce, utilizando-se a metodologia REML/BLUP. O experimento foi conduzido no município de Rio Largo, Estado de Alagoas, situado a 127 m de altitude, com latitude 9º27’S e longitude 35º27’W. Foram avaliados cinco clones (CL-2, CL-3, CL-4, CL-6 e CL-8) em delineamento experimental de blocos completos ...

Efficient ReML inference in variance component mixed models using a Min-Max algorithm.

open access: yesPLoS Computational Biology, 2022
Since their introduction in the 50's, variance component mixed models have been widely used in many application fields. In this context, ReML estimation is by far the most popular procedure to infer the variance components of the model.
