Method Details

getDim

public int getDim()

Specified by:

getDim in interface MultiVariateRealDistribution

pdf

public double pdf(double[] point)

Description copied from interface: MultiVariateRealDistribution

pdf of specified point in this distribution

Specified by:

pdf in interface MultiVariateRealDistribution

Parameters:

point - point to evaluate pdf at
