All Implemented Interfaces:

CondProbDistrib

public class UniformVector
extends AbstractCondProbDistrib

The uniform distribution over n-dimensional column vectors coming from a specified n-dimensional "box".

Constructor Summary

UniformVector(java.util.List params)
The constructor takes an even number of parameters.

Method Summary

double	getLogProb(java.util.List args, java.lang.Object value) Returns the natural log of the value returned by getProb.
double	getProb(java.util.List args, java.lang.Object value) For a discrete distribution, returns the conditional probability of childValue given the argument values args.
java.lang.Object	sampleVal(java.util.List args, Type childType) Samples a value according to this CPD given the args .

Constructor Detail

UniformVector

public UniformVector(java.util.List params)

The constructor takes an even number of parameters. For all i, 0<=i<=(n-1)/2, the (2i)-th parameter is treated as the lower bound of the generated vectors' i-th component, and every (2i+1)-th argument as the i-th component upper bound. All parameters must be of type Number.

Throws:

java.lang.IllegalArgumentException

Method Detail

getProb

public double getProb(java.util.List args,
                      java.lang.Object value)

Description copied from 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.

getLogProb

public double getLogProb(java.util.List args,
                         java.lang.Object value)

Description copied from interface: CondProbDistrib

Returns the natural log of the value returned by getProb.

Specified by:

getLogProb in interface CondProbDistrib

Overrides:

getLogProb in class AbstractCondProbDistrib

sampleVal

public java.lang.Object sampleVal(java.util.List args,
                                  Type childType)

Description copied from interface: CondProbDistrib

Samples a value according to this CPD given the args . The object returned should be of the specified type.
