least favorable configuration; asymptotic efficiency; Bechhofer procedure
In this paper properties of some ranking and selection procedures based on robust $L$-estimates of location parameter are studied. The least favorable configuration of parameters and the asymptotic efficiency relative to procedures based on sample means are found.
