ADMISSIBILITY AND Г-MINIMAXITY OF LOSSESTIMATORS IN MULTIVARIATE LINEAR MODEL
Admissible loss estimator r-minimax los

0 are known t \times n and m \times m matrices respectively \bar{B} = (X'G^{-1}X)^- X'G^{-1}y. It is proved that the uniformly minimum risk unbiased estimator of L, \bar{L}_{0} = (tr CV)SX(X'G^{-1}X)^...
ADMISSIBILITY OF SIMULTANEOUS ESTIMATION OF SEVERAL LOSSES
Loss estimator generalized Bayes estimat
2007/8/7
In this paper, admissibility and inadmissibility results of simultaneous estimation of losses of multivariate normal mean estimators are given. Admissible estimators for losses of usual estimators of ...
For the general fixed effects linear model: Y=Xτ+ε,ε～N(0,V)(or N(0,σ~2V)), V≥0, we obtain the necessary and sufficient condition for LY+α to be admissible for Sτ in the class of all estimators under m...
