Abstract
We consider a stage life testing model and assume that the information
at which levels the failures occurred is not available. In order to find estimates for
the lifetime distribution parameters, we propose an EM-algorithm approach which
interprets the lack of knowledge about the stages as missing information. Furthermore,
we illustrate the implementation diculties caused by an increasing number of stages.
The study is supplemented by a data example as well as simulations.
