Abstract |
|
|
| Balasooriya and Gadag (1994) proposed a location and scale invariant test based on the test statistic Zk for testing the k
upper outliers in two-parameter exponential sample. Kumar et al have proposed test statistics for testing multiple upper outlier detection
in gamma sample. In literature, various test statistics have been proposed to detect outliers in an exponential sample. Likes (1966) also
proposed a new test statistics to detect outlier in the exponential case. In this paper, the test statistic proposed by Likes has been used to
detect outliers in a two parameter gamma sample and the null distribution of the test statistics has been obtained. A simulation study is
carried out to compare the theoretical developments. |
