A family of estimators for estimating the population mean in simple random sampling under measurement errors
Sachin Malik, Jayant Singh, Rajesh Singh
In this article we have suggested an improved estimator for estimating the population mean in simple random sampling using auxiliary information under the presence of measurement e…
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…
A General Family of Estimators for Estimating Population Mean in Systematic Sampling Using Auxiliary Information in the Presence of Missing Observations
M. K. Chaudhary, Sachin Malik, Jayant Singh +1
This paper proposes a general family of estimators for estimating the population mean in systematic sampling in the presence of non-response adapting the family of estimators propo…
