Detection Of Many Outliers in the Two-Parameter Weibull Distribution

LI Yun-fei (School of Mathematics and Information,China West Normal University Nanchong Sichuan 637002)  
A method of detection for the upper outliers in the two-parameter Weibull distribution is discussed. The sample fractile and equivariant estimators of scale parameter of the extreme are used to construct the new test statistic——Z~* type statistic.The discussion of testing efficiency indicates the test statistic can avoid the masking effect.If there are many upper outliers in the sample,we can detect them by repeated use of the method.
