OptimStrat is a package intended to assist in the choice of the sample strategy to implement in a survey. It compares five strategies having into account the information available in an auxiliary variable and two superpopulation models, called working and true models.
The package includes a web-based application where the user can compare five sampling strategies in order to determine which one to implement in a survey.
The package also includes a function to perform the comparison mentioned above, as well as functions for stratifying the auxiliary variable and calculations of the variance of Stratified Simple Random Sampling and Pareto \(\pi\)ps.
