摘要
本文讨论了Weibull分布场合恒加寿命试验的点估计和近似区间估计,利用模拟方法说明所给方法的有效性.
In this paper, we discuss the parameter estimation of the constant stress accelerated life tests under the Weibull distribution. Some new estimates are given, and approximate confidence intervals are also derived with nonconstant shape parameter. The simulation results show that the new estimates and approximate confidence intervals are effective.
