Summary/Abstract: Using the information on two-auxiliary variables, three different exponentialchain-type estimators of population mean of study variable have been proposed intwo-phase (double) sampling. Properties of the proposed estimators have beenstudied and their performances are examined with respect to several well knownchain-type estimators. Empirical studies are carried out to support the theoreticalresults.
