Abstract We consider the estimation of the p -variate normal mean of $$Xsim mathcal {N}_p(theta ,I)$$ X∼Np(θ,I) under the quadratic loss function. We investigate the decision theoretic properties of debiased shrinkage estimator, the estimator which shrinks towards the origin for smaller $$Vert xVert ^2$$ ‖x‖2 and which is exactly equal to the unbiased estimator X for larger $$Vert xVert ^2$$ ‖x‖2 . Such debiased shrinkage estimator seems superior to the unbiased estimator X , which implies minimaxity. However, we show that it is not minimax under mild conditions.
摘要考虑了二阶损失函数下$$Xsim mathcal {N}_p(theta ,I)$$ X ~ N p (θ, I)的p变量正态均值的估计。我们研究了去偏收缩估计量的决策理论性质,对于较小的$$Vert xVert ^2$$‖x‖2,估计量向原点收缩,对于较大的$$Vert xVert ^2$$‖x‖2,估计量完全等于无偏估计量x。这种去偏收缩估计量似乎优于无偏估计量X,无偏估计量意味着极小。然而,我们证明在温和条件下它不是极小极大的。

Abstract In this work, we introduce a new chi-squared type test the odd Lindley exponentiated gamma distribution. The new test is an extension of the Nikulin–Rao–Robson test. The new test is tailored to fit the right censored data. The performance of the new test, as well as the baseline Nikulin–Rao–Robson test, are evaluated via numerical simulation. The new test, as well as the baseline Nikulin–Rao–Robson test, are also evaluated using the data. Furthermore, we present some characterization results.
