The Effect of Using Household as a Sampling Unit
研究了通过家庭抽样对个人估计的影响，识别了影响设计效应的关键因素，并利用普查和调查数据比较了不同设计下的效果。
The effect of sampling people through households is considered.Results on design effects for two stage surveys are reviewed and applied to give design effects of household samples relative to direct sampling of people.The main factors that determine the design effect are identified for the designs in which one person, or all people, are selected from each selected household.Within household correlation is only one factor.We show that the relationships between household size and the mean and variance within households are also important factors.Census and survey data are used to empirically compare the design effects for a range of estimators, variables and designs.
