Description Not Available
In the present study the question of developing the unbiased ratio type, product type, and ratio cum product type estimators has been taken up and appropriate estimators along with their variances have been worked out. The following estimates, the variances of the estimates and the variances of the estimates and the estimates of these variances are obtained by using the concept of multivariate symmetric means.
1. Multivariate unbiased ratio type estimator of the population mean using data on two or more supplementary variables.
2. Multivariate unbiased product type estimator.
3. Generalised multivariate unbiased estimate where p or the supplementary variables having positive correlation and q of them having negative correlation with the variable under study.
4. Unbiased ratio cum product type estimator.
An empirical study has been made by using these estimators and results rare included as illustration.
