BetaBinomial

public BetaBinomial(blang.core.IntVar realization,
                    java.util.function.Supplier<blang.core.IntVar> $generated__numberOfTrials,
                    java.util.function.Supplier<blang.core.RealVar> $generated__alpha,
                    java.util.function.Supplier<blang.core.RealVar> $generated__beta)

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

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 blang.core.IntVar realization()

Specified by:

realization in interface blang.core.UnivariateModel<blang.core.IntVar>

distribution

public static blang.core.IntDistribution distribution(blang.core.IntVar numberOfTrials,
                                                      blang.core.RealVar alpha,
                                                      blang.core.RealVar beta)

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.
