MAUSS-R is an open source generalized software for the determination of the sample allocation, developed using the R language and provided with a Java interface to facilitate the selection of data and parameters of interest.

The reference methodology is an extension of the Neyman allocation method to the case of several variables and adopts as a method of solving a generalization of the Bethel’s proposal (1989).

The generalized Bethel algorithm allows to calculate the sample allocation for stratified sampling designs: the overall sample size and the allocation among the different strata is determined starting from the constraints imposed in the survey on the accuracy of the estimates of interest.

The software in the current version allows the determination of the sample allocation in the multivariate case and for multiple domains of estimate for single selection stage samples.

The interface allows:

  • changing the default values of the processing parameters (such as the minimum number of units per stratum);
  • the management of the file containing the constraints of precision and the storing of different versions of the constraints and the obtained results;
  • the execution of the calculation of the optimal solution;
  • the comparison with the proportional allocation and equal;
  • viewing reports on population, the results and the comparison of the results obtained changing the constraints.
