Use of Domain Estimators with Unequal Probability in Sample Surveys
调查抽样中不等概率域估计量的使用
Unbiased estimates of population parameters can be obtained from a sample survey when the sample units are not the primary units of estimation, i.e., when the correspondence between the units selected in the sample and the units of interest is not one to one. The survey technique used was that of a mail questionnaire with direct interviews of a subsample of non-respondents. The estimation technique used was that of domain estimators with unequal probability. Feasible…
