Proportion Based Dual Unbiased Exponential Type Estimators of Population Mean
Keywords:
Auxiliary attribute, dual estimator, unbiased estimator, bias, mean square errorAbstract
Prior to the concept of auxiliary information, the estimator used for estimating the finite population mean was the sample mean estimator. By making use of auxiliary information, some new estimators of population mean were proposed from time to time to get more precise estimates. The importance of these estimators lies in that they estimate the population mean of the study variable
precisely by making use of the information of some other variable called the auxiliary variable whose information is readily available. Besides ratio, product, regression, and difference estimators, the exponential estimators were also proposed which may be employed even when there is a low degree of correlation between the study and auxiliary variable. This paper proposes dual unbiased exponential-type estimators in simple random sampling when the auxiliary information is qualitative in nature. The theoretical expressions of bias and mean square error (MSE) have been evaluated. A comparative study of MSE expressions of the estimators shows that the proposed estimators produce more efficient results than the existing sample mean estimator, the estimators of Naik and Gupta (1996), exponential estimators of Singh et al. (2007), and the family of exponential estimators proposed by
Zaman and Kadilar (2019). To support the claim of gain in efficiency, a numerical study is also carried out using the data of two populations.
