Estimating a Survival Curve When New Is Better Than Used
Article Abstract:
Reliability statistics theory now includes a variety of nonparametric classes of life distributions. They model qualitative characteristics of systems without adding constraints. However, inference results are more difficult to develop with these distributions. An estimation problem for these distributions with "New Better Than Used" means that the residual lifetime of a used item tends to be shorter than the lifetime of a new item.

Estimating the Shift to Wear-Out of Systems Having Exponential-Weibull Life Distributions
Article Abstract:
Complex mechanical systems, after a certain time, enter a wear-out phase. Failure rates of components tend to increase. Prior to the wear-out phase is a stable phase where systems have a constant failure rate. A Bayes adaptive procedure for estimating the change-point is developed. Results of numerical simulations are given in tables.
