TESTING IFR AND NBU CLASSES
Abstract
In this paper a test is proposed for testing whether a life distribution function F is IFR or not and another test for testing that F is NBU or not. The tests are shown to be consistent. Some selected critical values and powers are tabulated using Monte Carlo methods. Finally the IFR test is compared with the natural test for testing IFR class.
