Computational Approach to Generalized Ratio Type Estimator of Population Mean Under Two Phase Sampling
In the present draft, we propose the computational approach to generalized ratio type estimator of population mean of the main variable under study using auxiliary information. The expressions for the bias and mean square errors (MSE) have been obtained up to the first order of approximation. The minimum value of the MSE of the proposed estimator is also obtained for the optimum value of the ch...
متن کاملA ratio chain-type exponential estimator for finite population mean using double sampling
In this article, we have proposed a ratio chain-type exponential estimator for finite population mean of the study variable under double sampling scheme using auxiliary variables. The large sample properties of the suggested strategy are derived up to first order, of approximation, and its competence conditions are carried out under which the suggested estimator is performed better than the oth...
متن کاملModified Ratio cum Product Estimator for Estimation of Finite Population Mean with Known Correlation Coefficient
In sampling theory, a wide variety of techniques is used to obtain efficient estimators for the population mean. The commonly used method to obtain the estimator for population mean is simple random sampling without replacement (SRSWOR) when there is no auxiliary variable available. There are methods that use the auxiliary information of the study characteristics. If there exists an auxiliary v...
متن کاملRatio-Product Type Exponential Estimator For Estimating Finite Population Mean Using Information On Auxiliary Attribute
In practice, the information regarding the population proportion possessing certain attribute is easily available see Jhajj et.al. (2006). For estimating the population mean Y of the study variable y, following Bahl and Tuteja (1991), a ratio-product type exponential estimator has been proposed by using the known information of population proportion possessing an attribute (highly correlated wi...
متن کاملSeparate Ratio-product Estimator for Estimating Population Mean Using Auxiliary Information
This paper introduces an estimator of population mean Y of the study variable y using auxiliary variable x in stratified random sampling. The bias and variance of the proposed estimator have been derived under large sample approximation. Asymptotic optimum estimator (AOE) is identified with its approximate variance formula. Estimator based on “estimated optimum values” is also investigated. An ...
