Constructor and Description

Dirichlet(Simplex realization, java.util.function.Supplier<xlinear.Matrix> $generated__concentrations) Note: the generated code has the following properties used at runtime: - all arguments are annotated with a BlangVariable annotation - params additionally have a Param annotation - the order of the arguments is as follows: - first, all the random variables in the order they occur in the blang file - second, all the params in the order they occur in the blang file

Note: the generated code has the following properties used at runtime: - all arguments are annotated with a BlangVariable annotation - params additionally have a Param annotation - the order of the arguments is as follows: - first, all the random variables in the order they occur in the blang file - second, all the params in the order they occur in the blang file

Method Detail

builderFromCommandLine

public static Dirichlet.Builder builderFromCommandLine()

getRealization

public Simplex getRealization()

getConcentrations

public xlinear.Matrix getConcentrations()

main

public static void main(java.lang.String[] arguments)

Utility main method for posterior inference on this model

components

public java.util.Collection<blang.core.ModelComponent> components()

A component can be either a distribution, support constraint, or another model which recursively defines additional components.

Specified by:

components in interface blang.core.Model

generate

public void generate(java.util.Random rand)

Specified by:

generate in interface blang.core.ForwardSimulator

realization

public Simplex realization()

Specified by:

realization in interface blang.core.UnivariateModel<Simplex>

distribution

public static blang.core.Distribution<Simplex> distribution(Simplex realization,
                                                            xlinear.Matrix concentrations)

Returns an instance with fixed parameters values and conforming the Distribution interface. Useful when passing around distributions as parameters, e.g. for Dirichlet Process mixtures.
