双参数指数分布参数比率统计推断的研究

Inference of Parameters Ratio in Two-Parameter Exponential Distribution

本文在产品寿命服从双参数指数分布的无替换定数截尾寿命试验场合下,提出了两独立产品平均寿命比率的两个估计量,并研究了这两个比率估计量的渐近正态性和置信区间.然后通过数据模拟,进一步验证了所提出比率估计量的有效性.

Under the non-replacement fixed-number censored life time testing, two estimates of the ratio of two independently distributed two-parameter exponential distributions are proposed. The asymptotic normality and confidence intervals are established. Through simulation studies, the validation of proposed estimates is strengthened.
