摘要：
Let F(x) and G(x) be the absolutely continuous distribution functions of 2 life distributions with rF(x) and rG(x) as their respective hazard rates. In the class of increasing failure rate distributions, one-sided scale as well as one-sided location alternatives imply that 1 hazard rate is uniformly smaller than the other. A new distribution-free test for testing H0: rF(x) = rG(x) against HA: rF(x) .ltoreq. rG(x) is proposed. The test possesses robust asymptotic efficiency properties.
