Where MSE and MST are the mean-square error and mean-square treatment from an
analysis of variance performed on the ranked set sample data with the judgment class
used as a factor. This estimator has been shown to perform very well for small as well as
large ranked set samples, which is an improvement on Stokes [8] estimator. The
comparison will be based on the factors: coverage probability and width which seems to
be the major factors for comparison, see Mahmoudvand and Hassani [18], Terpstra and
Wang [17], Panichkitkosolkul [13], Panichkitkosolkul [14], and Kang and Schmeiser [19]
for discussion.
