An improved exponential ratio estimator for post-stratified sampling designs
This study proposes a new ratio-type exponential estimator for estimating the finite population mean under post-stratification. A simple random sample is first selected and later divided into post-strata using an auxiliary variable to improve the precision of estimation. The proposed estimator incorporates auxiliary in...
