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 ... WebOct 4, 2024 · The predictions coming from Mixed Models are called Best Linear Unbiased Prediction (BLUP), and they are called that way because they include the fixed and random effects of the model to provide a prediction. By including both fixed and random effects, Mixed Models allow a technique called ‘ shrinkage ’, or partial-pooling, which limits the ... loss of hair called

In statistics, best linear unbiased prediction (BLUP) is used in linear mixed models for the estimation of random effects. BLUP was derived by Charles Roy Henderson in 1950 but the term "best linear unbiased predictor" (or "prediction") seems not to have been used until 1962. "Best linear unbiased predictions" … See more In contrast to the case of best linear unbiased estimation, the "quantity to be estimated", $${\displaystyle {\tilde {Y_{k}}}}$$, not only has a contribution from a random element but one of the observed … See more Henderson explored breeding from a statistical point of view.
