Optimum Stratification in Bivariate Auxiliary Variables under Neyman Allocation

摘要

When the complete data set of the study variable is unknown it produces a possible stumbling block in attempting various stratification techniques. A technique is proposed under Neyman allocation when the stratification is done on the two auxiliary variables having one estimation variable under consideration. Because of complexities made by minimal equations, approximate optimum strata boundaries are obtained. An empirical study illustrates the proposed method when the auxiliary variables have standard Cauchy and power distributions.
