| Abstract | Test for exponentially against decreasing (increasing) variance remaining life distribution DVRL (IVRL) is introduced. We construct test statistic based on scaled total time on test (TTT)-transform, to test exponentiality versus DVRL (IVRL) class. The distribution of the statistic is investigated via simulation. An example of 40 patients suffering from blood cancer disease (leukemia) is considered as a practical application of the proposed test in the medical sciences. Keywords: Decreasing (Increasing) variance remaining life distribution DVRL (IVRL), Exponentiality, Total time on test (TTT-test). |
