A New Modified Approach for the Improvement of New Estimator Using Known Value of Downton’s Method as Auxiliary Information for Estimating the Population Variance

M. A. Bhat, S. A. Mir, S. Maqbool, T. A. Raja, Ab. Rauf Shah, Z. M. Dar & Immad A. Shah · Asian Journal of Agricultural Extension, Economics & Sociology · 2018

In the present study we have suggested a newly modified ratio estimator for estimating the population variance by utilizing the auxiliary information of Downton's method. Properties associated with proposed estimators are assessed by mean square error and bias through numerical d...

Estimate of Population Variance by Introducing Gini’s Mean Difference as Auxiliary Information

M. A. Bhat, S. Maqbool, S. A. Mir, T. A. Raja, Ab. Rauf, N. A. Sofi & Immad A. Shah · Journal of Scientific Research and Reports · 2018

In this study we have introduced a new reliable and robust ratio estimator for estimating the population variance by utilizing the auxiliary information as Gini’s mean difference. Efficiency conditions along with bias and mean square error has been worked out through a numerical...
