| Abstract: | We obtain the maximum likelihood estimator and the simulated moment estimator of parameters of two-parameter exponential distribution with censored sample based on tampered failure rate model under step-stress accelerated life testing. Thereafter we show the feasibility of this method by using the Monte-Carlo simulation. |
| Keywords: | two-parameter exponential distribution censored sample step-stress accelerated life testing tampered failure rate model maximum likelihood estimator simulated moment estimator |
