Abstract
We consider the problem of estimating the scale parameter θθ of the shifted exponential distribution with unknown location based on a type II progressively censored sample. Under a large class of bowl-shaped loss functions, a smooth estimator, that dominates the minimum risk equivariant estimator of θθ, is proposed. A numerical study is performed and shows that the improved estimator yields significant risk reduction over the MRE.
