Blup statistics
WebThe use of BLUPs to predict random effects was first described by C. R. Henderson. He developed the mixed model equations (MME, see equation . [2]) for LMMs in order to calculate BLUPs of breeding values (or any random effect) and BLUEs of fixed effects.. Let’s have a look at how solutions are obtained from a linear mixed model. WebMay 4, 2024 · BLUP is a mixed model equation system involving fixed and random (including animal genetic) effects for the prediction of animals’ breeding values. With genomic information and genomic relationship matrices becoming available, A is still needed in recent genetic evaluation models, such as single-step genomic BLUP [ 2 , 3 ] and …

WebJun 20, 2024 · The REML/BLUP statistics are analyses that can be used as selective criteria in the routine of maize breeding programs. The present study aims to determine the genetic potential in crosses of landrace populations applying the REML/BLUP methodology, and to identify populations for the synthesis of ne … WebSelection based on information from family members of the fish and using Best Linear Unbiased Prediction (BLUP) statistics was fully applied to the breeding program of Nile tilapia. BLUP provides for very accurate estimates of genetic values, thereby giving accurate ranking of the fish, because it accounts for non-genetic differences between ...

WebAbstract. In this article, kriging is equated with spatial optimal linear prediction, where the unknown random-process mean is estimated with the best linear unbiased estimator. This allows early appearances of (spatial) prediction techniques to be assessed in terms of how close they came to kriging.
