Heuristic Algorithm for Univariate Stratification Problem
José Brito, Gustavo Semaan, Leonardo de Lima +1
In sampling theory, stratification corresponds to a technique used in surveys, which allows segmenting a population into homogeneous subpopulations (strata) to produce statistics w…

An Integer Programming Formulation Applied to Optimum Allocation in Multivariate Stratified Sampling
Jose Andre de Moura Brito, Gustavo Silva Semaan, Pedro Luis do Nascimento Silva +1
The problem of optimal allocation of samples in surveys using a stratified sampling plan was first discussed by Neyman in 1934. Since then, many researchers have studied the proble…

An Exact Algorithm for the Stratification Problem with Proportional Allocation
Jose Brito, Mauricio Lila, Flavio Montenegro +1
We report a new optimal resolution for the statistical stratification problem under proportional sampling allocation among strata. Consider a finite population of N units, a random…
