| Abstract: | In this paper,for zero-failure data（ti,ni）at moment ti,if the prior distribution of the failure probility pi=p{T（？）ti}is quasi-Gamma distribution,the author gives the pi Bayesian estimation and hierarchical Bayesian estimation and the reliability under zero-failure data condition is also obtained. |
