In this paper, we discuss the outlier procedures on test for Weibull or Extreme-value distribution. The exact distribution of the Dixon statistic is derived. We present a new F-type statistic,and give its percentile values in Weibull or Extreme-value distribution case.We also compare some methods for testing outliers in Weibull or Extreme-value sampling by Monte-Carlo method, its is shown that the F-type procedure is the best.
