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…
Difference-type estimators for estimation of mean in the presence of measurement error
Viplav Kr. Singh, Rajesh Singh, Florentin Smarandache
In this paper we have suggested difference-type estimator for estimation of population mean of the study variable y in the presence of measurement error using auxiliary information…
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…
A family of median based estimators in simple random sampling
Hemant K. Verma, Rajesh Singh, Florentin Smarandache
In this paper we have proposed a median based estimator using known value of some population parameter(s) in simple random sampling. Various existing estimators are shown particula…
An improved estimator for population mean using auxiliary information in stratified random sampling
Sachin Malik, Viplav Kumar Singh, Rajesh Singh
In the present study, we propose a new estimator for population mean of the study variable y in the case of stratified random sampling using the information based on auxiliary vari…
An almost unbiased estimator for population mean using known value of population parameter(s)
Sachin Malik, Rajesh Singh, SB Gupta
In this paper we have proposed an almost unbiased estimator using known value of some population parameter(s) with known population proportion of an auxiliary variable. A class of…
