On moments of folded and doubly truncated multivariate extended skew-normal distributions
Christian E. Galarza, Larissa A. Matos, Dipak K. Dey +1
This paper develops recurrence relations for integrals that relate the density of multivariate extended skew-normal (ESN) distribution, including the well-known skew-normal (SN) di…
Finite mixture modeling of censored and missing data using the multivariate skew-normal distribution
Francisco H. C. de Alencar, Christian E. Galarza, Larissa A. Matos +1
Finite mixture models have been widely used to model and analyze data from a heterogeneous populations. Moreover, data of this kind can be missing or subject to some upper and/or l…
Moments of the doubly truncated selection elliptical distributions with emphasis on the unified multivariate skew- distribution
Christian E. Galarza, Larissa A. Matos, Victor H. Lachos
In this paper, we compute doubly truncated moments for the selection elliptical (SE) class of distributions, which includes some multivariate asymmetric versions of well-known elli…
Objective Bayesian analysis for spatial Student-t regression models
Jose A. Ordoñez, Marcos O. Prates, Larissa A. Matos +1
The choice of the prior distribution is a key aspect of Bayesian analysis. For the spatial regression setting a subjective prior choice for the parameters may not be trivial, from…
