Abstract |
|
|
| In this paper, we have suggested a general class of dual to product-cum-dual to ratio type estimators of finite
population mean using an auxiliary variable x that is correlated with the variable y of interest. The proposed class of
estimators includes several known estimators based on transformation in auxiliary variable x. The bias and mean squared
error (MSE) expressions of the proposed class of estimators have been obtained to the first degree of approximation. We
have compared the proposed class of dual to product-cum- dual to ratio type estimators of finite population mean to various
existing ratio, product, and ratio-cum-product type estimators and shown that the suggested class of estimators is better
than other existing estimators under some realistic conditions. |
