本文首先从理论上介绍了若干种不等概率抽样方法，它们的估计量、估计量的方差及其估计，其中包括有放回ppz及pps抽样，不放回不等概率抽样中的brewer 、 durbin 、 sampford 、 desraj ， murthy 、 rao - hartley - cochran等人的方法；其次，在rao和bayless两人就样本单元数n = 2的情形对上述抽样方法进行比较的基础上，将总体随机地分成两个子总体，视每个子总体取自不同的线性超总体，在文中，我们利用计算机实现随机分组，并通过画图比较各方法估计量的稳定性，结果表明，对变异系数c . v . ( x )较大的总体而言，两个超总体之间的微小差异将对估计量的稳定性产生很大的影响，从而说明rao和bayless的比较结果还不够完善。 | | 7. | Then , with the concept of accumulated failure probability , the proposed approach combines the least ? quares method with bayes " theorem , takes advantage of the parameter estimation for single weibull distribution to each derived subgroup data set , and estimates the parameters of each subpopulation . the estimates given by this paper also satisfy the maximum likelihood equation . the mean time to failure and the reliability estimation of the mixed population are given
