- Title
A Generalized Difference-cum-Ratio Type Estimator for the Population Variance in Double Sampling.
- Authors
Jhajj, H. S.; Walia, G. S.
- Abstract
For estimating the population variance of variable under study, a generalized difference-cum-ratio type estimator has been proposed. Expressions for bias and mean square error have been obtained using random sampling at both the phases. The expressions have also been derived using simple random sampling at both the phases as a special case. Then the comparison has been made with the regression-type estimator and sample variance. Results have also been illustrated numerically and graphically.
