ABSTRACT
A very active area of research in Bayesian nonparametrics concerns the
definition of priors that depend on covariates and that, then, lend
themselves to be applied to regression modelling. In this talk we
describe two possible constructions of nonparametric priors for
vectors of probablility distributions. Both rely on suitable
transformations of completely random measures: in one case dependence
between random probability distributions is established by means of a
Lévy copula, while, in the other, dependence is induced by introducing
a common component for the marginal measures. The computational
algorithms that allow for a full Bayesian analysis in these settings
will be presented and an illustration involving a two-sample dataset
will be discussed.




Con i migliori saluti,
Silvia Bozza
