Resumen


In this paper, we have taken under considerations two auxiliary variables used as stratification variables and single study
variable. For obtaining the optimum strata boundaries, we have solved the non linear equations using dynamic programming that
resulted in more efficient results rather than obtained on using single study variable and single auxiliary variable. The proposed
method is illustrated by using different distributions followed by stratification variables.
