Some Improved Estimators for Ratio and Product of two Population Means Using auxiliary character and two phase Sampling scheme in the Presence of Non-Response

B. B. Khare, Utkarsh

Abstract


Some improved estimators for ratio and product of two population means using auxiliary character and two phase sampling scheme in the presence of non-response have been proposed and their properties are studied. A comparative study is made with relevant estimators. The empirical studies show the efficiency of the proposed estimators with the relevant estimators.

Keywords


Population means, two phase sampling, study character, auxiliary character, relative bias and mean square error.
