M. A. Bhat, S. Maqbool, S. A. Saraf, S. H. Malik, Yasmeena Ismail & Mir Subzar · Journal of Scientific Research and Reports · 2018

By adapting the scheme of modification technique, we have developed some new ratio type variance estimators to estimate the finite population variance for skewed populations under survey. We have also derived the functions of efficiency to intensify the quality of efficacy of new...

Variance Estimation Using Linear Combination of Skewness and Quartiles

M. A. Bhat, S. Maqbool, S. A. Saraf, Ab. Rouf & S. H. Malik · Advances in Research · 2018

In this paper we have suggested Modified ratio type variance estimators where in our aim is to estimate the population variance in the presence of outliers, when there is strong correlation between auxiliary variable and study variable by using, the linear combination of skewness...
