Abstract |
|
|
| By taking advantage of the correlation between the study variable and the auxiliary variable, ratio, product, and regression estimators are widely used to estimate the population mean of the study variable or other parameters of interest. In this paper an exponential ratio-type estimator using two auxiliary variables for estimation of a finite population mean has been proposed. Mean Square Error expression of the proposed estimator has been derived up to first degree of approximation. The efficiency conditions of the proposed ratio estimator have been studied. The theoretical result is illustrated with real data sets for numerical comparisons.
