Improved ratio-type estimators of finite population variance using quartiles
In this paper we have proposed some ratio-type estimators of finite population variance using known values of parameters related to an auxiliary variable such as quartiles with their properties in simple random sampling. The suggested estimators have been compared with the usual unbiased and ratio estimators and the estimators due to [2], [12, 13, 14] and [3]. An empirical study is also carried...
متن کاملImproved Exponential Estimator for Population Variance Using Two Auxiliary Variables
In this paper exponential ratio and exponential product type estimators using two auxiliary variables are proposed for estimating unknown population variance y S . Problem is extended to the case of two-phase sampling. Theoretical results are supported by an empirical study.
متن کاملImproved estimation of population variance using information on auxiliary attribute in simple random sampling
Singh and Kumar (2011) suggested estimators for calculating population variance using auxiliary attributes. This paper proposes a family of estimators based on an adaptation of the estimators presented by Kadilar and Cingi (2004) and Singh et al. (2007), and introduces a new family of estimators using auxiliary attributes. The expressions of the mean square errors (MSEs) of the adapted and prop...
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 کاملAn Improved Ratio Type Predictive Estimator for Estimating Finite Population Mean Using Auxiliary Information
In the present article, motivated by Jeelani et al. (2013), we have made an attempt to develop an improved ratio type estimator of population mean using predictive method of estimation by using linear combination of coefficient of skewness and the quartile deviation of auxiliary variable. The mathematical expressions for the bias and mean squared error (MSE) of the proposed estimator up to the ...
