Variance Estimation for Survey Data with Composite Imputation and Nonnegligible Sampling Fractions
复合插补与不可忽略抽样比下调查数据的方差估计
This article considers variance estimation for Horvitz–Thompson–type estimated totals based on survey data with imputed non-respondents and with nonnegligible sampling fractions. A method based on a variance decomposition is proposed. Our method can be applied to complicated situations where a composite of some deterministic and/or random imputation methods is used, including using imputed data in subsequent imputations. Although here linearization or Taylor expansion–type…
