saeb

The Basic Education Evaluation System (Saeb) is a series of large-scale
external assessments conducted by Inep (National Institute for
Educational Studies and Research) to diagnose the state of basic education
in Brazil and identify factors that may affect student performance.
This dataset contains the standardized math scores of 12th graders from 160
randomly selected schools in Rio de Janeiro who took the 2021 exam.

datasets

Fit mixed-effects location scale models with spike-and-slab priors on the location random effects to identify units with unusual residual variances. The method is described in detail in Carmo, Williams and Rast (2025) <https://osf.io/sh6ne>.
