Abstract
Ratio estimation under two-phase simple random sampling is studied. A new linearisation variance estimator that makes more complete use of t he sample data than a standard one is proposed. A jackknife variance e stimator and its linearised version are also obtained. Unconditional a nd conditional repeated sampling properties of these variance estimato rs are studied through simulation. Applications to 'mass' imputation u nder two-phase sampling and deterministic imputation for missing data are also given.
