提出了定数截尾下两参数Weibull分布精确联合置信区间估计的一种方法,并给出了可靠度的一个保守的置信下限,最后用模拟方法将其和已有的联合置信区间估计方法进行比较,表明文章的估计方法更好.本方法亦可推广到双边定数截尾的情形.
A new method to obtain the exact joint confidence region of the two-parameter Weibull distribution is proposed,and a conservative lower confidence bound for the reliability function is derived. At last, this method is compared with the one that has been proposed by Chen[2],and is verified better. The new method can also be generalized to double Type Ⅱ censored sample.
