Functions in this package provide solution to classical problem in
survey methodology - an optimum sample allocation in stratified sampling
schemes. In this context, the optimal allocation is in the classical
Tschuprov-Neyman's sense and it satisfies additional lower or upper bounds
restrictions imposed on sample sizes in strata. There are few different
algorithms available to use, and one them is based on popular sample
allocation method that applies Neyman allocation to recursively reduced set of
strata.
This package also provides the function that computes a solution to the minimum
sample size allocation problem, which is a minor modification of the classical
optimium sample allocation. This problem lies in the determination of a vector
of strata sample sizes that minimizes total sample size, under assumed fixed
level of the pi-estimator's variance. As in the case of the classical optimal
allocation, the problem of minimum sample size allocation can be complemented
by imposing upper bounds constraints on sample sizes in strata.
