Two parameter modified ratio estimators with two auxiliary variables for the estimation of finite population mean
Abstract
The present paper deals with some two parameter modified ratio estimators for the estimation of finite population means with known skewness and correlation coefficient on two auxiliary variables. It has been shown that the proposed modified ratio estimators perform better than the simple random sampling without replacement (SRSWOR) sample mean and some of the existing ratio estimators for certain natural populations available in the literature.
