Estimation procedure combines the use of individual observations and subgroup screening. An initial estimate for μ is based on the trimmed means of the tri means and screen the subgroups. Then, the resulting estimator for μ from the remaining subgroups is sued to screen the individual outliers in the remaining subgroups.
