摘要
JamesBerger(1976年)获得X是位置参数θ的尾-Minimaxity.本文将此结果推广一般的不等压缩情形获得是尾-Minimaxity,其中r(X)diag(r_1(X)=diag(r_1(X),……r,(X)),B=(b_(ij)p×p.
James Berger(1976)has proved that X is Tail-Minimaxity for lo-cation vector θ. This paper extends the result to the unequal compactmess and proves that δ(X)=X is tail-Minimaxity for θwhere r(X)=diag(r_1(X)=…,r,(X))and B=()b_(ij)_p×p.
