The Dirichlet Process is the De Finetti mixing distribution for the CRP. • Graphical model visualization This means, when we integrate out G, we get the CRP:

"WebMar 1, 2012 · The Poisson-Dirichlet distribution (PD) is a one-parameter family but we only need the distribution with parameter 1, so we ignore the parameter altogether. It is best introduced with the help of the Griffiths-Engen-McCloskey distribution (GEM). The latter is also called the “stick-breaking” distribution. " - Griffiths-engen-mccloskey
