Abstract | |||||||||||||||
| This paper presents a Bayesian nonparametric approach to survival analysis based on arbitrarly right censored data. The first aim will be to show that the neutral to the right process is the natural prior to use in this context. Secondly, the properties of a particular neutral to the right process, the beta-Stacy process are examined. Finally, the connections between some Bayesian bootstraps and the beta-Stacy process are investigated.
