Multivariate dual to ratio type estimators using arithmetic, geometric and harmonic means in simple random sampling
Rajesh Singh, Prayas Sharma
Auxiliary variable is extensively used in survey sampling to improve the precision of estimates. Whenever there is availability of auxiliary information, we want to utilize it in t…
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,…
Method of estimation in the presence of non-response and measurement errors simultaneously
Prayas Sharma, Rajesh Singh
The present paper discusses the problem of estimating the finite population mean of study variable in simple random sampling in the presence of non response and response error toge…
Efficient class of estimators for population median using auxiliary information
Prayas Sharma, Rajesh Singh
This article suggests an efficient class of estimators of population median of the study variable using an auxiliary variable. Asymptotic expressions of bias and mean square error…
Improved ratio type estimator using two auxiliary variables under second order approximation
Prayas Sharma, Rajesh Singh
In this paper, we have proposed a new Ratio Type Estimator using auxiliary information on two auxiliary variables based on Simple random sampling without replacement (SRSWOR). The…
