摘要：

The adaptive trimmed means of Hogg (1974) and modified by De Wet and van Wyk (1978) are studied in this paper for finite sam-ples. They are shown to have good robustness and efficiency properties for sample sizes 20 and larger. Confidence intervals based on these estimators are also considered and found to be fairly robust for sample sizes 40 and larger. © 1979, Taylor & Francis Group, LLC. All rights reserved.
