Generalized class of estimators for finite population mean when study variable is qualitative in nature
Prayas Sharma, Hemant K. Verma, Rajesh Singh
This paper suggests a generalized class of estimators for population mean of the qualitative study variable in simple random sampling using information on an auxiliary variable. As…
Improved estimator of finite population mean using auxiliary attribute in stratified random sampling
Hemant K. Verma, Prayas Sharma, Rajesh Singh
The present study discuss the problem of estimating the finite population mean using auxiliary attribute in stratified random sampling. In this paper taking the advantage of point…
Exponential ratio-product type estimators under second order approximation in stratified random sampling
Rajesh Singh, Prayas Sharma, Florentin Smarandache
Singh et al (20009) introduced a family of exponential ratio and product type estimators in stratified random sampling. Under stratified random sampling without replacement scheme,…
