Abstract
|
In this approach we consider the problem of estimating the p-dimensional location parameter
in spherically symmetric models. The invariant quadratic loss function is taken into account when
the scalar scale component is assumed to be unknown. The aim is to study the performance of a dominant class of estimators over the unrestricted estimator, when the components of location parameter are restricted to be nonnegative.
