A Hierarchical Dynamic Beta Regression Model of School Performance in the Brazilian Mathematical Olympiads for Public Schools
Alexandra M. Schmidt, Caroline P. de Moraes, Helio S. Migon
The Brazilian Mathematical Olympiads for Public Schools (OBMEP) is held every year since 2005. In the 2013 edition there were over 47,000 schools registered involving nearly 19.2 m…
Population counts along elliptical habitat contours: hierarchical modelling using Poisson-lognormal mixtures with nonstationary spatial structure
Alexandra M. Schmidt, Marco A. Rodríguez, Estelina S. Capistrano
Ecologists often interpret variation in the spatial distribution of populations in terms of responses to environmental features, but disentangling the effects of individual variabl…
Measuring the vulnerability of the Uruguayan population to vector-borne diseases via spatially hierarchical factor models
Hedibert F. Lopes, Alexandra M. Schmidt, Esther Salazar +2
We propose a model-based vulnerability index of the population from Uruguay to vector-borne diseases. We have available measurements of a set of variables in the census tract level…
