Variance estimation using linear combination of non conventional measures and coefficient of kurtosis

Bhat, M.A., Maqbool, S. and Mir Subzar

Abstract: 

In the present study we propose new modified ratio estimators for estimating the population variance by using auxiliary information of non conventional location measures, non conventional measures of dispersion and coefficient of kurtosis. The properties associated with the proposed estimators are assessed by mean square error and compare with the existing estimators. By this comparison we conclude that our proposed estimators are more efficient than existing estimators. Numerical study is also provided to support the theoretical results.
