Abstract
Neyman and Scott [6] have considered the ideas of outlier-proneness and outlier-resistance of families of distributions, on the other hand Green [4] has considered the ideas of outlier-proneness and outlier-resistance of individual distributions. In this note, it is shown that the family of Weibull distributions is outlier-prone completely, and some properties of outlier-proneness and outlier-resistance of distributions are shown.
