Invited discussion on “Latent Nested Nonparametric Priors” by F. Camerlenghi, D. B. Dunson, A. Lijoi, I. Prünster and A. Rodríguez
Published in Bayesian Analysis, 2019
In this work, we comment on the article by Camerlenghi and co authors, proposing an approximation to their latent nested process, that we obtain by truncating a priori the stick-breaking construction of a nested Dirichlet Process.
We implement the model using JAGS and extend to the case when more than two subpopulations are compared.
