POST-STRATIFICATION
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:
