—This presentation looks at two statistics that can be used in developing new tests of discordancy in circular samples from von Mises distribution. We derive the approximate distributions for both statistics. Consequently, an alternative test of discordancy is proposed based on the circular distance between sample points. The advantage of the test is that(More)

Consequently, extensive research has been conducted on developing outlier detection procedures so that outliers may be properly managed. However, no work has been done on the problem of(More)
