| Abstract: | For exponential life data with varying censoring time, this paper gives approximation to the distribution of parameter estimation using saddlepoint approximation. Based on the saddlepoint approximation, this paper provides approximative lower confidence limit of reliability. Finally, the numerical simulation shows the proposed methods are feasible. |

| Keywords: | data with varying censoring time saddlepoint approximation reliability confidence limit |
