The efficiencies of the ratio- type estimators have been increased by using linear transformation on auxiliary variable in the literature. But such type of estimators requires the additional knowledge...
Exact Computation of Minimum Sample Size for Estimating Proportion of Finite Population
Exact Computation Minimum Sample Size Estimating Proportion Finite Population
2010/4/30
In this paper, we develop an exact method for the determination of the minimum sample
size for estimating the proportion of a finite population with prescribed margin of error and
confidence level. ...
