Gibbs Partitions (EPPF's) Derived From a Stable Subordinator are Fox H and Meijer G Transforms (2007)

Ho, Man-Wai, James, Lancelot F., Lau, John W.

This paper derives explicit results for the infinite Gibbs partitions generated by the jumps of an $\alpha-$stable subordinator, derived in Pitman \cite{Pit02, Pit06}. We first show that for general...

A Bayes method for a Bathtub Failure Rate via two $\mathbf{S}$-paths (2007)

Ho, Man-Wai

A class of semi-parametric hazard/failure rates with a bathtub shape is of interest. It does not only provide a great deal of flexibility over existing parametric methods in the modeling aspect but...

Bayesian Nonparametric Estimation of a Unimodal Density via two $\mathbf{S}$-paths (2006)

Ho, Man-Wai

A Bayesian nonparametric method for unimodal densities on the real line is provided by considering a class of species sampling mixture models containing random densities that are unimodal and not...

A Bayes method for a monotone hazard rate via S-paths (2006)

Ho, Man-Wai

A class of random hazard rates, which is defined as a mixture of an indicator kernel convolved with a completely random measure, is of interest. We provide an explicit characterization of the...

Coagulation Fragmentation Laws Induced By General Coagulations of Two-Parameter Poisson-Dirichlet Processes (2006)

Ho, Man-Wai, James, Lancelot F., Lau, John W.

Pitman~(1999) describes a duality relationship between fragmentation and coagulation operators. An explicit relationship is described for the two-parameter Poisson-Dirichlet laws, with parameters...

A class of random hazard rates, which is defined as a mixture of an indicator kernel convolved with a completely random measure, is of interest. We provide an explicit characterization of the...
