Estimation of mean using dual-to-ratio and difference-type estimators under measurement error model
Viplav Kumar Singh, Rajesh Singh
In sample survey, when data is collected, it is assumed that whatever is reported by respondent is correct. However, given the issues of prestige bias, personal respect, respondent…
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…
A generalised family of ratio product estimator using transformation equation
Viplav K. Singh, Rajesh Singh
In this paper we deal with the estimation of population variance of the study variable y using auxiliary information on variable x. A family of ratio and product-type estimators ar…
Some improved estimators for estimating population mean in stratified random sampling
Rajesh Singh, Viplav K. Singh, A. A. Adewara
Some improved estimators are proposed for estimating the population mean in stratified sampling in the presence of auxiliary information. Mean square error (MSE) of the proposed es…
Use of Auxiliary Information in Variance Estimation
Jayant Singh, Viplav K. Singh, Sachin Malik +1
This paper proposes a class of ratio type estimators of finite population variance, when the population variance of an auxiliary character is known. Asymptotic expression for mean…
An Improved Estimator In Systematic Sampling
Rajesh Singh, Sachin Malik, Viplav K. Singh
In this paper we have adapted Bahl and Tuteja (1991) estimator in systematic sampling using auxiliary information. Using Bedi (1996) transformation an improved estimator is also pr…
