Public Methods

Method	Description
Clone ( ) : object	Creates a new object that is a copy of the current instance.
DistributionFunction ( ) : double	This method is not supported.
Fit ( double observations, double weights ) : IDistribution	Fits the underlying distribution to a given set of observations.
Generate ( int samples ) : double[][]	Generates a random vector of observations from the current distribution.
NormalDistribution ( double mean, double covariance ) : System	Constructs a multivariate Gaussian distribution with given mean vector and covariance matrix.
NormalDistribution ( int dimension ) : System	Constructs a multivariate Gaussian distribution with zero mean vector and unitary variance matrix.
ProbabilityDensityFunction ( ) : double	Gets the probability density function (pdf) for this distribution evaluated at point `x`. The Probability Density Function (PDF) describes the probability that a given value `x` will occur.

Creates a new object that is a copy of the current instance.
