`DirichletProcessMap` — The integer-map Dirichlet process distribution

Usage

DirichletProcessMap(keys: IntSet, alpha: Double, dist: Distribution<a>) → Distribution<IntMap<a>>

Arguments

keys:: The integer keys identifying the samples
alpha:: The concentration parameter controlling how often new values are drawn
dist:: The base distribution on shared values

Description

Draw one exchangeable Dirichlet process value for each supplied integer key. The result has exactly the supplied key set, and entries assigned to the same cluster share one value drawn from dist.

Examples

~DirichletProcessMap(branches(tree), 1, LogNormal(0,1))
