Exponential type estimators for ratio and product of two population means using auxiliary character in the presence of non-response

Kamlesh Kumar


This paper presents exponential type estimators for ratio and product of two population means using known population mean of auxiliary character in the presence of non-response. The expressions for relative bias and mean square error of the proposed estimators have been derived. The theoretical and empirical studies have been done to demonstrate the superiority of the proposed estimators over the other estimators.


Bias, mean square error, non-response, study character, auxiliary character.
