Dual to Separate Product Type Exponential Estimator in Sample Surveys

PP: 89-96
Hilal A. Lone, Rajesh Tailor,
This paper addresses the problem of estimation of finite population mean in case of post-stratification. In this paper dual to separate product type exponential estimator is proposed using the same approach adopted by Srivenkataramana [15] and Bandhyopadhyaya [2]. Conditions under which the proposed estimator is more efficient than usual unbiased estimator, usual separate product type estimator, dual to separate product type estimator and separate product type exponential estimator are obtained. The bias and mean squared error expressions are obtained upto the first degree of approximation. An empirical study has been carried out to demonstrate the performance of the proposed estimator.
