Interface MultiRandomDistribution

All Superinterfaces:

java.io.Serializable

All Known Implementing Classes:

MultiGaussianDistribution

public interface MultiRandomDistribution
extends java.io.Serializable

This interface must be implemented by all the package's classes implementing a multi-variate random distribution.

Method Summary

int	dimension() Returns the dimension of the vectors handled by this random distribution.
double[]	generate() Generates a pseudo-random vector.
double	probability(double[] v) Returns the probability (density) of a given vector.

Method Detail

dimension

int dimension()

Returns the dimension of the vectors handled by this random distribution.

Returns:

The generated vectors' dimension.

generate

double[] generate()

Generates a pseudo-random vector. The vectors generated by this function must follow the pseudo-random distribution described by the object that implements it.

Returns:

A pseudo-random vector.

probability

double probability(double[] v)

Returns the probability (density) of a given vector.

Parameters:

v - A vector.

Returns:

The probability of the vector v.
