SAE models for indicators in the unit interval: The tipsae R package and its Shiny interface

The tipsae R package is a dedicated tool for mapping proportions and indicators defined on the unit interval, e.g., common poverty and inequality measures, in the framework of small area estimation. It implements Beta-based Bayesian Hierarchical models at the area-level through Stan language. A set of diagnostics, exploratory analysis and complementary tools, such as benchmarking and variance smoothing methods, complete the package. To enhance accessibility for practitioners, we have developed a user-friendly Shiny application alongside the R package. The purpose of this paper is to illustrate its potential by describing the workflow of a typical small area analysis and by providing the underlying R code. The current version 0.0.18 is avalaible on https://cran.rproject.org/web/packages/tipsae/index.html
