gov.sandia.cognition.statistics.distribution.MultinomialDistribution.Domain

All Implemented Interfaces:

java.lang.Iterable<Vector>, java.util.Collection<Vector>, java.util.Set<Vector>

Enclosing class:

MultinomialDistribution

public static class MultinomialDistribution.Domain
extends java.util.AbstractSet<Vector>

Allows the iteration through the set of subsets. That is, how many ways can we label "numTrials" objects with "numClasses" labels. BE CAREFUL, before iterating through all members of a Domain, as this grows as a factorial!!! (See the size() method for the exact size.)
