Webcess) have the so-called Griffiths-Engen-McCloskey or GEM(jß) distribution (see, e.g., Johnson et al. 1997, p. 237), where the parameter ß is defined as the terminal time divided by the variance rate of the underlying gamma process. The considerable advan-tage that these asymptotic considerations bring to WebFor consistency in posterior inference and predictive distributions, we efficiently characterize random probability measures whose limits are the global and local DPs to approximate the HDP from the stick-breaking formulation with the GEM (Griffiths-Engen-McCloskey) random variables.

The GEM Distribution is a special case of the Dirichlet process. Named for Griffiths, Engen, and McCloskey’s early work in this space, the GEM distribution is a Dirichlet process which takes one parameter — we could write the above Dir(1,1,1,1,1,1,1) as GEM(1).
