Improved Generalized Ratio-Cum-Product Estimation |
|
| Authors: | R Karan Singh Gurdeep Singh |
| Abstract: | In this paper, a generalized ratio-cum-product estimator for estimating the ratio (product) of two population means using auxiliary information on two other variables is given of which the estimators by SINGH (1969) and SHAH and SHAH (1978) are particular cases. The estimator is regeneralized when the covariance between two auxiliary variables is known. |
