A Modified Ratio-Cum-Product Estimator of Finite Population Mean in Stratified Random Sampling Rajesh Tailor1)
This paper suggests a ratio-cum-product estimator of finite population mean using a correlation coefficient between study variate and auxiliary variate in stratified random sampling. Bias and mean squared expressions of the suggested estimator are derived and compared with combined ratio estimator a...
