메소드 설명
Clone ( ) : object

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

DistributionFunction ( int x ) : double

Gets the cumulative distribution function (cdf) for the this distribution evaluated at point x.

The Cumulative Distribution Function (CDF) describes the cumulative probability that a given value or any value smaller than it will occur.

Fit ( double observations, double weights ) : IDistribution

Fits the underlying distribution to a given set of observations.

PoissonDistribution ( double lambda ) : System

Creates a new Poisson distribution with the given lambda.

ProbabilityMassFunction ( int x ) : double

Gets the probability mass function (pmf) for this distribution evaluated at point x.

The Probability Mass Function (PMF) describes the probability that a given value x will occur.
