Abstract: In this paper, the problem of estimation of variance has been considered when the missing data have been imputed with the ratio method of imputation. Two alternative variance estimators have been proposed. Relative efficiencies of the proposed estimators have been compared with the existing alternative Jackknife estimator proposed by Rao and Sitter [1995. Variance estimation under two-phase sampling with application to imputation for missing data. Biometrika 82, 453-460] through empirical study. Empirical investigation shows that the proposed estimators fare better than the Rao and Sitter's [1995. Variance estimation under two-phase sampling with application to imputation for missing data. Biometrika 82, 453-460] estimator.
