Abstract :
In this paper, we propose a new ratio type
estimator for double sampling with two auxiliary
variables. The expressions for bias and mean square
error (MSE) of the proposed estimator have been
obtained. Some realistic conditions have been obtained
under which the proposed estimator is more efficient
than the usual unbiased well-known existing estimators
of double sampling using two auxiliary variables for
population mean and it was found to be more efficient
in many situations.
Keywords :
Double Sampling; Ratio-Type Estimator; Bias; Mean Square Error (MSE); Auxiliary variable.
