Estimation of Finite Population Variance Using Scrambled Responses in the Presence of Auxiliary Information
In this paper, a new estimator for estimating the finite population variance of a sensitive variable based on scrambled responses collected using a randomization device is introduced. The estimator is then improved by using known auxiliary information. The estimators due to Das and Tripathi (1978: Sankhya) and Isaki (1983: JASA) are shown to be special cases of the proposed estimator. Numerical...
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 کاملVariance estimation for the finite population distribution function with complete auxiliary information
The authors develop jackknife and analytical variance estimators for the estimator of Chambers & Dunstan (1986) and Rao, Kovar & Mantel (1990) of the finite population distribution function, using complete auxiliary information. They also describe the associated model and show the design consistency of the variance estimators, whose small-sample performance is examined through a limited simulat...
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 کاملSome improved estimators of finite population quantile using auxiliary information in sample surveys
The problem of quantile estimation using quantiles Qx( ) in which the order of the auxiliary variable is di4erent from that of the main variable to be estimated, Qy( ), is considered. Certain new estimators for the -quantile have been proposed for any sampling design. The e4ect of this modi"cation on the standard estimators, ratio, position, strati"cation, regression and di4erence type estimato...
