Constructor Summary

TrivialPiHelper()

 

Method Summary
Distribution	compute_pi(ConditionalDistribution px, Distribution[] pi_messages)           This helper is called only when there are no parents of a variable; in that case, the marginal distribution is just the distribution conditional on the parents, and pi is the marginal distribution.
static riso.general.SeqTriple[]	description()           Returns a description of the sequences of distributions accepted by this helper -- namely exactly one AbstractDistribution.

compute_pi

public Distribution compute_pi(ConditionalDistribution px,
                               Distribution[] pi_messages)
                        throws java.lang.Exception

This helper is called only when there are no parents of a variable; in that case, the marginal distribution is just the distribution conditional on the parents, and pi is the marginal distribution. So this method just returns the variable's conditional distribution.
