Smooth nonparametric estimation of the hazard and hazard rate functions from record-breaking data. (English) Zbl 0803.62028

Summary: Often in industrial quality control experiments and destructive stress testing, only values smaller than all previous ones are observed. Here, from such record-breaking data, non-parametric estimation of the hazard function and the hazard rate is considered. For a single record-breaking sample, consistent estimation is not possible except in the extreme tails of the distribution. Hence, replication is required and for \(m\) such independent record-breaking samples, strong consistency of the estimators is established as \(m\to \infty\). Also, the hazard function estimators are shown to be asymptotically normal. Finally, for small \(m\), the mean squared errors and biases of the estimators are examined through computer simulations.
