PReMiuM: An R Package for Profile Regression Mixture Models Using Dirichlet Processes
PReMiuM is a recently developed R package for Bayesian clustering using a Dirichlet process mixture model. This model is an alternative to regression models, non- parametrically linking a response vector to covariate data through cluster membership ...

Distributions of Functionals of the two Parameter Poisson-Dirichlet Process [PDF]
The present paper provides exact expressions for the probability distribution of linear functionals of the two–parameter Poisson–Dirichlet process. Distributional results that follow from the application of an inversion formula for a (generalized) Cauchy–

pyrichlet: A Python Package for Density Estimation and Clustering Using Gaussian Mixture Models
Bayesian nonparametric models have proven to be successful tools for clustering and density estimation. While there exists a nourished ecosystem of implementations in R, for Python there are only a few. Here we develop a Python package called pyrichlet,

Dynamic clustering via asymptotics of the dependent Dirichlet process mixture [PDF]
This paper presents a novel algorithm, based upon the dependent Dirichlet process mixture model (DDPMM), for clustering batch-sequential data containing an unknown number of evolving clusters.

ABSTRACT This study investigates how companies across different industries emphasize themes within Integrated Reporting (IR), as promoted by the International Integrated Reporting Council (IIRC). As IR gains relevance for advancing Corporate Social Responsibility (CSR) and Environmental, Social, and Governance (ESG) disclosure, understanding sectoral ...

Coupling Fluid Neutrals to Gyrokinetic Plasma Dynamics for Edge and SOL Turbulence Simulations
ABSTRACT Accurate modeling of turbulent transport in magnetic confinement fusion devices requires extending first‐principles gyrokinetic simulations from the core to the edge and scrape‐off layer (SOL), where additional physics—particularly plasma–neutrals interactions—must be included.

A semiparametric Bayesian approach to the analysis of financial time series with applications to value at risk estimation [PDF]
Financial time series analysis deals with the understanding of data collected on financial markets. Several parametric distribution models have been entertained for describing, estimating and predicting the dynamics of financial time series ...
