- All Implemented Interfaces:
- CondProbDistrib
public class Iota
- extends DetCondProbDistrib
CPD that takes a set of size one as an argument, and defines a probability
distribution concentrated on the single element of that set. If the
argument set is empty, the distribution is concentrated on Model.NULL.
If the set has size greater than one, the getProb
and
sampleVal
methods throw IllegalArgumentExceptions.
The name comes from the iota operator in logic.
