Variational Full Bayes Lasso: Knots Selection in Regression Splines
Larissa Alves, Ronaldo Dias, Helio S. Migon
We develop a fully automatic Bayesian Lasso via variational inference. This is a scalable procedure for approximating the posterior distribution. Special attention is driven to the…
The effects of degrees of freedom estimation in the Asymmetric GARCH model with Student-t Innovations
T. C. O. Fonseca, V. S. Cerqueira, H. S. Migon +1
This work investigates the effects of using the independent Jeffreys prior for the degrees of freedom parameter of a Student-t model in the asymmetric generalised autoregressive co…
Reference Bayesian analysis for hierarchical models
Thaís C. O. Fonseca, Helio S. Migon, Heudson Mirandola
This paper proposes an alternative approach for constructing invariant Jeffreys prior distributions tailored for hierarchical or multilevel models. In particular, our proposal is b…
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…
