U. Gather et al., ASYMPTOTICALLY EFFICIENT NONITERATIVE ESTIMATORS OF A COMMON PARAMETER FROM INDEPENDENT SAMPLES, Statistics, 28(3), 1996, pp. 187-200
This paper presents a general approach for constructing asymptotically
efficient noniterative estimators of a common parameter based on seve
ral independent, but related populations. As an important application
we discuss the estimation of a common relative risk in stratified samp
les. Various relative risk estimators are compared by Monte-Carlo resu
lts. An example is given for illustrating their application.
