The hazard function is an important characteristic for the analysis of reliability data. It is therefore of interest to see under what conditions it can be expressed as the product of a function of the variable and a function of the parameter. We show that such a factorization can be...

In life tests, the progressive Type-II censoring methodology allows for the possibility of censoring a number of units each time a failure is observed. This results in a large number of possible censoring plans, depending on the number of both censoring times and censoring numbers. Employing...

We introduce a random power record model and explore small-sample and asymptotic properties of the associated record times and record counts. We establish a hierarchical relationship between several previously studied record models and show that this model incorporates all of them.
