Abstract |
|
|
| In this paper, a ratio-cum-product type estimator in case of post-stratification has been proposed. The bias and
mean squared error of the proposed estimator are obtained up to the first degree of approximation. The mean squared error
for the proposed estimator has been obtained and it has been shown that the proposed estimator is more efficient than the
usual unbiased estimator and the estimators suggested by Ige and Tripathi [7]. Theoretical conditions are obtained under
which the proposed estimator is more efficient than considered estimators. Finally, in order to find the merits of the proposed
estimator an empirical study has been carried out. |
