نویسندگان
چکیده
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 proposed estimators have been compared with two-phase ratio estimator and some other chain ratio type estimators. The performances of the proposed estimators have been supported with a numerical illustration.

Efficient Use of Auxiliary Variables in Estimating Finite Population Variance in Two Phase Sampling
This paper presents some chain ratio-type estimators for estimating finite population variance using two auxiliary variables in two phase sampling set up. The expressions for biases and mean squared errors of the suggested classes of estimators are given. Asymptotic optimum estimators (AOE’s) in each class are identified with their approximate mean squared error formulae. The theoretical and em...
متن کاملModified Sampling Strategies Using Correlation Coefficient for Estimating Population Mean
This paper proposes two sampling strategies based on the modified ratio estimator using the population mean of auxiliary variable and population correlation coefficient between the study variable and the auxiliary variable by Singh and Tailor (2003) for estimating the population mean (total) of the study variable in a finite population. A comparative study is made with usual sampling strategies...
متن کاملEstimation of the Finite Population Mean in Two Phase Sampling When Auxiliary Variables Are Attributes
We consider the problem of estimating the finite population mean in two phase sampling when some information on auxiliary attributes is available. It is shown that the proposed estimator is more efficient than the usual mean estimator, the S. Bahl and R.K. Tuteja (Ratio and product type exponential estimators, Information and Optimization Sciences 12 (1), 159–163, 1991) estimator and a family o...
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 کاملMultivariate Estimators for Two Phase Sampling
The auxiliary information has always been a source of improvement in estimation of certain population characteristics. Several estimators have been developed in single and two phase sampling which utilizes information on auxiliary variables as well as auxiliary attributes. The classical estimators which use information on auxiliary variables are the ratio and regression estimators as given in H...
