Multivariate Jacobi and Laguerre polynomials, infinite-dimensional extensions, and their probabilistic connections with multivariate Hahn and Meixner polynomials [PDF]
, 2011 Multivariate versions of classical orthogonal polynomials such as Jacobi, Hahn, Laguerre, Meixner are reviewed and their connection explored by adopting a probabilistic approach.

Poisson Latent Feature Calculus for Generalized Indian Buffet Processes [PDF]
, 2014 The purpose of this work is to describe a unified, and indeed simple, mechanism for non-parametric Bayesian analysis, construction and generative sampling of a large class of latent feature models which one can describe as generalized notions of Indian ...

On a Beta-Gamma Discrete Distribution for Thunderstorm Count Modeling with Risk Analysis
MathematicsRisk management is vital for financial institutions to evaluate and mitigate potential losses. Thunderstorm count modeling with risk analysis is used by various sectors, such as insurance and utility companies, to forecast storm recurrence, analyze risk,

Beta-Negative Binomial Process and Exchangeable Random Partitions for Mixed-Membership Modeling [PDF]
, 2014 The beta-negative binomial process (BNBP), an integer-valued stochastic process, is employed to partition a count vector into a latent random count matrix.

On homogeneous skewness of unimodal distributions [PDF]
, 2009 We introduce a new concept of skewness for unimodal continuous distributions which is built on the asymmetry of the density function around its mode. The asymmetry is captured through a skewness function.

Bayesian approach to LR assessment in case of rare type match: careful derivation and limits
, 2016 The likelihood ratio (LR) is largely used to evaluate the relative weight of forensic data regarding two hypotheses and for its assessment Bayesian methods are widespread in the forensic field.

Revista Colombiana de Estadística, 2009 When analyzing data in the presence of over dispersion, the usual practice is to assume a common dispersion parameter to all observations. However, there are situations where the assumption of homogeneity of the dispersion parameter does not hold.
