Testing against HNBUE with randomly censored data

• The "harmonic new better than used in expectation" (HNBUE) class of life distributions contains all the more familiar classes from reliability theory such as the "increasing failure rate" (IFR) and "new better than used" (NBU), while still allowing one to formulate interesting inequalities comparing such distributions with the memoryless exponential distribution. In this paper test statistics based on the product-limit estimator are derived for testing the hypothesis of HNBUE versus exponentiality given a sample of censored observations from the life distribution of interest. A study of the asymptotic relative efficiency focusses on the loss of information due to censoring.
