Best Linear Unbiased Estimation in Linear Models
where X is a known n × p model matrix, the vector y is an observable ndimensional random vector, β is a p × 1 vector of unknown parameters, and ε is an unobservable vector of random errors with expectation E(ε) = 0, and covariance matrix cov(ε) = σV, where σ > 0 is an unknown constant. The nonnegative definite (possibly singular) matrix V is known. In our considerations σ has no role and hence ...
متن کاملBarankin Vector Locally Best Unbiased Estimates
The Barankin bound is generalized to the vector case in the mean square error sense. Necessary and sufficient conditions are obtained to achieve the lower bound. To obtain the result, a simple finite dimensional real vector valued generalization of the Riesz representation theorem for Hilbert spaces is given. The bound has the form of a linear matrix inequality where the covariances of any unbi...
متن کاملRandom Degrees of Unbiased Branches
In our previous published research we discovered some very difficult to predict branches, called unbiased branches that have a “random” dynamical behavior. We developed some improved state of the art branch predictors to predict successfully unbiased branches. Even these powerful predictors obtained very modest average prediction accuracies on the unbiased branches while their global average pr...
متن کاملSome properties of the best linear unbiased estimators in multivariate growth curve models
The purpose of this article is to build a class of the best linear unbiased estimators (BLUE) of the linear parametric functions, to prove some necessary and sufficient conditions for their existence and to derive them from the corresponding normal equations, when a family of multivariate growth curve models is considered. It is shown that the classical BLUE known for this family of models is t...
متن کاملIdentifying single genes of large effect in quantitative traits using best linear unbiased prediction.
The recent discovery of a major gene for rapid postweaning growth has reinforced the hypothesis that other quantitative continuous traits may be influenced by single genes of large effect. However, most methods for the detection of such genes rely on the discovery of multimodality in the population frequency distribution. The complicating effects of environment and artificial selection make the...
