This paper addresses the problem of estimating the population variance of variable of interest using information on an auxiliary variable in sample surveys. A new class of ratio-type estimators is proposed. In addition to some existing estimators, large number of consistent and inconsistent estimators has been identified as a member of the proposed class of(More)
This paper suggests the difference method of estimation of the population mean of the study variable using information on an auxiliary variable with its properties. The optimum estimator in the suggested method has been identified alongwith its mean square error formula. It has been identified that the suggested method is more general and efficient than(More)
