Bounded risk estimation of a linear combination of location parameters in negative exponential distributions via three-stage sampling

Eiichi Isogai and Andreas Futschik

Communications in Statistics - Theory and Methods, 2018, vol. 47, issue 15, 3728-3733

Abstract: The paper deals with the problem of bounded risk point estimation for a linear combination of location parameters of two negative exponential distributions. Isogai and Futschik considered the situation when the location and scale parameters are all unknown. They proposed purely sequential procedures and gave second order expansions of the average sample sizes and risks. In this paper we propose three-stage procedures and derive second order expansions of the average sample sizes and risks. Further, we compare the results with those from previous work.
