%description
In the field of stratified sampling design, this package offers an
approach for the determination of the best stratification of a sampling
frame, the one that ensures the minimum sample cost under the condition to
satisfy precision constraints in a multivariate 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; the fitness of all individuals is evaluated
applying the Bethel-Chromy algorithm to calculate the sampling size
satisfying precision constraints on the target estimates. Functions in the
package allows to: (a) analyse the obtained results of the optimisation
step; (b) assign the new strata labels to the sampling frame; (c) select a
sample from the new frame accordingly to the best allocation. Functions
for the execution of the genetic algorithm are a modified version of the
functions in the 'genalg' package. M.Ballin, G.Barcaroli (2020)
