IMPROVING ON MINIMUM RISK EQUIVARIANT AND LINEAR MINIMAX ESTIMATORS OF BOUNDED MULTIVARIATE LOCATION PARAMETERS Authors:

open access: yes, 2014
We propose improvements under squared error loss of the minimum risk equivariant and the linear minimax estimators for estimating the location parameter θ of a p-variate spherically symmetric distribution, with θ restricted to a ball of radius m centered

The Generalized Moment-Transmuted Cauchy Distribution: A Heavy-Tailed Family with Controllable Finite Moments

open access: yes
The Cauchy distribution is a fundamental heavy-tailed model whose practical use is often limited by the non-existence of finite moments. In this paper, we propose the Generalized Moment-Transmuted Cauchy (GMTC) distribution by applying a generalized ...

Estimation of the parameters in a two linear regression equations system with identical parameter vectors

open access: yes
For two normal linear models with some of the parameters identical, a new estimator of the parameters is proposed and its statistical property is established. Two seemingly unrelated regression models with identical parameters are also considered.

Efficiency of Feasible Weighted Least Squares Estimators of the Center and Radius of A Spherical Surface

open access: yes, 2007
: A linear model based on the spherical coordinate system is employed for fitting a spherical surface to a data set obtained by a coordinate measuring machine (CMM). In practice, measurement data may have unequal accuracy on the different coordinate axes,
