三、指数型分布函数参数的区间估计 1.关于区间估计的基本概念在确定和了解产品的可靠性指标时,通常都是在规定的试验条件下,投入一定数量的样品进行寿命试验,测量发生故障或失效的时间。由于这些样品一般都已作过可靠性筛选和例行试验,因此在可靠性试验时,大部分样品均已进入偶然失效期,其分布函数基本上属于指数分布。有些产品虽并不服从指数分布,如
Interval Estimation of Exponential Distribution Function Parameters 1. Basic Concepts of Interval Estimation When determining and understanding the reliability index of a product, usually a certain number of samples are put into service for life test under the specified test conditions and the measurement takes place Failure or failure of the time. Since these samples have generally been subjected to reliability screening and routine testing, most of the samples have entered the accidental expiration date during the reliability test, and their distribution functions are basically exponential. Although some products do not obey the exponential distribution, such as
