| Modifier and Type | Method and Description | 
|---|---|
| double | density(double[] x)Returns the probability density function (PDF) of this distribution
 evaluated at the specified point  x. | 
| int | getDimension()Gets the number of random variables of the distribution. | 
| void | reseedRandomGenerator(long seed)Reseeds the random generator used to generate samples. | 
| double[] | sample()Generates a random value vector sampled from this distribution. | 
| double[][] | sample(int sampleSize)Generates a list of a random value vectors from the distribution. | 
double density(double[] x)
x. In general, the PDF is the
 derivative of the cumulative distribution function. If the derivative
 does not exist at x, then an appropriate replacement should be
 returned, e.g. Double.POSITIVE_INFINITY, Double.NaN, or
 the limit inferior or limit superior of the difference quotient.x - Point at which the PDF is evaluated.x.void reseedRandomGenerator(long seed)
seed - Seed with which to initialize the random number generator.int getDimension()
