| Abstract: | In this paper, we give a statistical analysis method for randomly censored exponential life date under constant stress accelerated life testing models. We obtain the LSE about the accelerated coefficients a and b. Finally, we give an example of random simulation. The results show that the method given above is more accurate. |
