Abstract: A class of exponential ratio-cum-exponential dual
to ratio estimators for estimating a finite population mean in
double sampling scheme is proposed. The expressions for bias
and mean square error (MSE) of the proposed estimator have
been derived for two different cases. An asymptotic expression
for mean square error is obtained. Empirical studies are carried
out to illustrate the performance of the constructed estimator
over other estimators.
Keywords: Exponential ratio-cum-dual to ratio estimator, bias, mean squared error, auxiliary information, double sampling.
