Ratio Estimators in Simple Random Sampling Using Information on Auxiliary Attribute
Rajesh Singh, Pankaj Chauhan, Nirmala Sawan +1
Some ratio estimators for estimating the population mean of the variable under study, which make use of information regarding the population proportion possessing certain attribute…
Improved Exponential Estimator for Population Variance Using Two Auxiliary Variables
Rajesh Singh, Pankaj Chauhan, Nirmala Sawan +1
In this paper exponential ratio and exponential product type estimators using two auxiliary variables are proposed for estimating unknown population variance . Problem is ex…
Improvement in Estimating Population Mean using Two Auxiliary Variables in Two-Phase Sampling
Rajesh Singh, Pankaj Chauhan, Nirmala Sawan +1
This study proposes improved chain-ratio type estimator for estimating population mean using some known values of population parameter(s) of the second auxiliary character. The pro…
