  2. First, this paper gives an introduction of some methods of unequal probability sampling, their estimators and variance estimators, including sampling with pps with replacement, methods of sampling without replacement suggested by brewer, durbin, sampford, des raj, murthy, rao - hartley - cochran. then, at the basis of rao and bayless ' s study, we consider that population can be splited two random subpopulations, which are respectively drawn from different infinite super - populations, and compare the stabilities of estimators of the methods that given above. we find that the minor difference between two super - populations has great effect on the efficiency of the estimators for the population with moderately large coefficient of variation ( c. v. )

    本文首先從理論上介紹了若干種不等概率方法,它們的估計量、估計量的方差及其估計,其中包括有放回ppz及pps,不放回不等概率中的brewer 、 durbin 、 sampford 、 desraj , murthy 、 rao - hartley - cochran等人的方法;其,在rao和bayless兩人就本單元n = 2的情形對上述方法進行比較的基礎上,將總體隨機地分成兩個子總體,視每個子總體取自不同的線性超總體,在文中,我們利用計算機實現隨機分組,並通過畫圖比較各方法估計量的穩定性,結果表明,對變異系c . v . ( x )較大的總體而言,兩個超總體之間的微小差異將對估計量的穩定性產生很大的影響,從而說明rao和bayless的比較結果還不夠完善。
