摘要：
The problem of testing exponentiality against decreasing (increasing) variance remaining life distribution DVRL (IVRL) is investigated. For this aging properties, a nonparametric procedure (U-Test) is presented. The percentiles of this test are tabulated for sample sizes n = 5(1)40. It is shown that the proposed test is simple, has high relative efficiency for some commonly used alternatives and enjoys a good power. Data of 40 patients suffering from blood cancer disease (Leukemia) is considered as a practical application of the proposed test in the medical sciences. (C) 2003 Elsevier Inc. All rights reserved.
