Xiaofei Zhang / Abstract: Imputation can be used to complete records for a subsample of a large sample, when the subsample of the large sample has incomplete records. Data may be missing due to nonresponse or due to design. We give several mean estimation procedures based on nearest neighbor imputation for both nonresponse and design missing. We also give design consistent variance estimators for the mean estimators.
