"A measure of efficiency loss for the precision of estimates implied by sampling fractions reduction is described here....A study of the sampling fractions needed to guarantee a given precision level to estimate characteristics...is also performed. An application of the methodology suggested is included. The example is based on household characteristics investigated in [Brazil's]... Census of 1980, with estimates published at a county level and for the set of alternative sampling fractions for the 1990... Census." (SUMMARY IN ENG)
这里描述了一种因抽样比例降低所隐含的估计精度的效率损失度量……还进行了一项关于为保证估计特征达到给定精度水平所需抽样比例的研究。文中包含了对所建议方法的应用。该示例基于1980年[巴西]人口普查中所调查的家庭特征，估计数据在县级公布，且针对1990年……人口普查的一系列替代抽样比例。 （英文摘要）
