Journal ArticleDOI
Improving on the positive part of the UMVUE of a noncentrality parameter of a noncentral chi-square distribution
TL;DR: In this article, the authors give an explicit estimator dominating the positive part of the UMVUE of a noncentrality parameter of the noncentral χ 2 n (μ/2) with degree of freedom n and unknown parameter μ.
Journal ArticleDOI
An extended class of minimax generalized Bayes estimators of regression coefficients
TL;DR: This work derives minimax generalized Bayes estimators of regression coefficients in the general linear model with spherically symmetric errors under invariant quadratic loss for the case of unknown scale from Maruyama and Strawderman's estimators.
Journal ArticleDOI
A unified and generalized set of shrinkage bounds on minimax Stein estimates
TL;DR: In this paper, an increasing sequence of bounds on the shrinkage constant of Stein-type estimators were given for the case of spherical symmetry, spherical symmetry and unimodality, and scale mixtures of normals.
Journal Article
Combining inventory estimates with possibly biased auxiliary information
TL;DR: It is conjecture that investigators are often unsure of the possible bias in their auxiliary information, and thus the risk of the usual composite estimator can be greater than that of the sample mean.
Journal ArticleDOI
All estimates with a given risk, Riccati differential equations and a new proof of a theorem of Brown
TL;DR: In this article, the authors give a general method for finding estimates that have risk functions identical to that of a given inadmissible estimate in the case of more than one dimension, but in one dimension no such assumption is made.
