| Abstract: |
| In this paper, we study the problem of estimation for product failure rate based on Poisson distribution. By using the method of Bayesian statistical inference, the Bayesian estimation and related properties of product failure rate with truncated gamma distribution as prior distribution is presented, which generalize the results of Bayesian estimation when gamma distribution as prior distribution. |
