An interface which all user-defined conditional probability
distributions (CPDs), as well as the { are expected to implement.
|
public interface CondProbDistrib {
For a discrete distribution, returns the conditional probability of
childValue given the argument values args.
For a continuous distribution, returns the conditional probability
density at childValue.
|
double getProb( List args, Object childValue );
| Returns the natural log of the value returned by getProb. |
double getLogProb(List args, Object childValue);
Samples a value according to this CPD given the args
. The object returned should be of the specified type.
|
Object sampleVal( List args, Type childType );
