We suggest various RSS strategies to estimate the scale parameter. Their performances in terms of GV are compared with SRS strategy. Finally, we illustrate the minimum values of set size, n, based on RSS, which would result in smaller GV than that based on SRS. © 2014 Taylor and Francis Group, LLC.Mahidol UniversityMathematicsArticleSCOPUS10.1080/03610918.2012.698776
