NPflow

Overview

NPflow is a package for performingBayesianestimation of Dirichlet process mixtures of multivariate skew\(t\)-distributions. It isespecially oriented towards flow-cytometry data preprocessingapplications, but can be useful for numerous other applications.

The main function of the package isDPMpost().

The method implemented in this package is detailed in the followingarticle:

Installation

The easiest way to getNPflow is to install it fromCRAN:

install.packages("NPflow")

Or to get the development version fromGitHub:

#install.packages("devtools")devtools::install_github("sistm/NPflow",ref="CRANrelease")
