Abstract:

In this paper, a comparison for the power and efficiency of a set empirical distribution function(EDF) goodness of fit tests for the Laplace distribution is studied. Moreover, a new method to improve the power of these tests under the ranked set sampling is introduced. Using simulation, under ranked set sampling (RSS), the test are more powerful than their counterparts in simple random sampling (SRS) is shown. Also, the percentage points of these tests under the null hypotheses is obtained.
