Abstract : This paper
proposes two classes
of chain
ratio-type estimators
for finite population mean Y
of the study variate y using
two auxiliary variables in double sampling. Expressions for biases and mean
squared errors have been derived. Asymptotic
optimum estimator {AOE''s) in each
class is identified with approximate MSE formula. The performances of the constructed estimators have
been studied with the help of numertcal
illustrations.
Keywords : Study variate,
Auxiliary variate,
Bias and Mean squared errors,
