Summary
We study admissibility of a subclass of generalized Bayes estimators of a multivariate normal vector in the case where the variance is unknown, under scaled quadratic loss. Minimaxity is established for some of these estimators.

概括
我们研究了在方差未知的情况下,在缩放二次损失下,多元法向量的广义贝叶斯估计子类的可接受性。为其中一些估计器建立了极小值。
