For these reasons, they have been extensively studied in the literature. Despite of the richness of related contributions, there are still special aspects of these models that are worthwhile focusing. In this discussion paper we aim to present some contributions, in the frame of a Bayesian approach and by using some very basic notions of stochastic ordering. date: 2012 date_type: published publication: Journal of Reliability and Statistical Studies volume: 5 publisher: Ankur Printing Palace pagerange: 63-82 refereed: TRUE issn: 0974-8024 official_url: http://jrss.in/data/5S06.pdf citation: Foschi, Rachele and Spizzichino, Fabio Ageing and risk aspects in predictive inference based on proportional Hazard Models.
