Improved exponential type mean estimators for non-response case using two concomitant variables in simple random sampling
This paper addresses new exponential estimators for population mean in case of non-response on both the study and the concomitant variables using simple random sampling. The expressions for theoretical bias and mean square error of new estimators are derived up to first-order approximation and compa...
