...te and multidomain case. This approach is based on the use of the genetic algorithm: each solution (i.e. a particular partition in strata of the sampling frame) is considered as an individual in a population to be evolved; the fitness of all individuals is evaluated by calculating (using the Bethel-Chromy algorithm) the sampling size satisfying accuracy constraints on the target estimates.
The package covers all the phases, from the optimisation of the sampling frame, up to the design of the stratified sample, ending with the selection of the units.
