Equiprecisional allocation and optimum stratification

Abstract

In this work, we introduced the equiprecisional allocation int he context of the problem of optimum stratification in accordance with DALENIUS, as a procedure which allows us to improve the precision of the estimator with respect to the strategy (simple ranodm samplein, x),x being the sampling mean of the elementary observations obtained by s.r.s. We included some comparisions of the precisions obtained throught diverse and already known allocations and on incorporating the optimum stratification in each case.

Keywords:

• Survey sampling
• optimum stratification
• sampling allocation
