Bayesian Nonparametric Erlang Mixture Modeling for Survival Analysis
Yunzhe Li, Juhee Lee, Athanasios Kottas
We develop a flexible Erlang mixture model for survival analysis. The model for the survival density is built from a structured mixture of Erlang densities, mixing on the integer s…
Erlang mixture modeling for Poisson process intensities
Hyotae Kim, Athanasios Kottas
We develop a prior probability model for temporal Poisson process intensities through structured mixtures of Erlang densities with common scale parameter, mixing on the integer sha…
Modelling for Poisson process intensities over irregular spatial domains
Chunyi Zhao, Athanasios Kottas
We develop nonparametric Bayesian modelling approaches for Poisson processes, using weighted combinations of structured beta densities to represent the point process intensity func…
A New Family of Error Distributions for Bayesian Quantile Regression
Yifei Yan, Athanasios Kottas
We propose a new family of error distributions for model-based quantile regression, which is constructed through a structured mixture of normal distributions. The construction enab…
