At some time in the distant past, n objects, from a population with life distribution F, were put in use; whenever an object failed, it was promptly replaced. At some time $\tau$, long after the start of the process, a statistician starts observing the n objects in use at that time; he knows the age of each of those n objects, and observes each of them for a fixed length of time $T\le \infty$, or until failure, whichever occurs first. In the case where T is finite, some of the observations may be censored; in the case where $T=\infty$, there is no censoring. The total life of an object in use at time $\tau$ is a length- biased observation from F. A nonparametric estimator of the (cumulative) hazard function is proposed, and is used to construct an estimator of F which is of the product-limit type. Strong uniform consistency results (for $n\to \infty)$ are obtained. An ``Aalen-Johansen'' identity, satisfied by any pair of life distributions and their (cumulative) hazard function, is used for obtaining rate of convergence results.}, reviewer = {P.Gaenssler}, identifier = {04126492}, }
