英文摘要 | Two estimators for a finite population variance have been proposed using multivariate auxiliary information. Both the estimators are superior to Arcos and Rueda [1] as well as Isaki [2]. Further one of them is unbiased up to first order approximation. Computationally these estimators need only the additional information about the correlation coefficients among the variables. |
