The problem of efficient stratification in the case of skewed population is considered.Four stratification methods are examined.A new adjusted geometric stratification method is introduced.
This method is compared by simulation with Consumer DNA Test the Dalenius-Hodges cumulative root frequency method, the geometric method proposed by Gunning and Horgan [2], and the power method offered Dryer Filter Spigot by Plikusas in [6].The simulation results show that in most cases considered the power method is the most efficient one.
