| Abstract | ||
| In this paper, we propose a number of families of estimators of ratio and regression to estimate the population variance using auxiliary information in two phase sampling, the bias and the mean square error expression for the above estimators are obtained up to terms of order only and calculate minimizing the for all estimators and also the generalization of estimators. | ||
