Some properties of the “new better than used in failure rate” (NBUFR) and the “new better than used in expectation” (NBUE) classes of life distributions are given. These properties include moment inequalities and moment generating functions behaviors. In addition, nonparametric estimation and testing of the survival functions of these classes are discussed.
