Robustness of the best linear unbiased estimator and predictor in linear regression models [PDF]
, 1990 summary:If is shown that in linear regression models we do not make a great mistake if we substitute some sufficiently precise approximations for the unknown covariance matrix and covariance vector in the expressions for computation of the best linear ...

Location Of Objects with a High Degree of Inner Precision
Slovak Journal of Civil Engineering, 2014 Let us have two coordinate systems in a plane. In the first one (e.g. JTSK) the accuracy of the coordinate estimators is signicantly lower than the accuracy in the other system (the inner system of an object).

Consistency of the Estimator for the Common Mean in Fixed-Effect Meta-Analyses
Axioms, 2023 Fixed-effect meta-analyses aim to estimate the common mean parameter by the best linear unbiased estimator. Besides unbiasedness, consistency is one of the most fundamental requirements for the common mean estimator to be valid.

Upper bounds for the Euclidean distances between the BLUPs
Special Matrices, 2018 In this article we consider the general linear model {y, X ß, V} where y is the observable random vector with expectation X ß and covariance matrix V. Our interest is on predicting the unobservable random vector y* which comes from y* = X* ß + ƹ* where ...

Linearity of Unbiased Linear Model Estimators
, 2022 Best linear unbiased estimators (BLUE’s) are known to be optimal in many respects under normal assumptions. Since variance minimization doesn’t depend on normality and unbiasedness is often considered reasonable, many statisticians have felt that BLUE’s ...
