By: Manish Trivedi and D.shukla.

Abstract: It is often seen that a population having large number of elements remains unchanged in several occasions but the value of unit's changes. The sample surveys are also not limited to one-time inquiries. In this paper, an estimator has been introduced under successive surveys. This estimator is unbiased and efficient over Post-stratification estimator. In this paper, minimum variance of the optimum estimator has been derived and comparative study is incorporated.

Key Words: Post-stratification, Successive Occasions, Optimum, Estimator
