Summ. & Conclusions - Bayes estimation of the parameters and the relia
bility function based on type-1 and type-2 censored samples from a Par
eto failure model is considered. The analysis is extended to situation
s wherein the exact survival times are not available but only the numb
er of deaths in prescribed time intervals is recorded. Bayes calculati
ons can be implemented easily by means of the Gibbs Sampler.
