Public Methods

Method Description
ChiSquareDistribution ( int degreesOfFreedom ) : System

Constructs a new Chi-Square distribution with given degrees of freedom.
Clone ( ) : object

Creates a new object that is a copy of the current instance.
DistributionFunction ( double x ) : double

Gets the cumulative distribution function (cdf) for the χ² 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

This method is not supported.
ProbabilityDensityFunction ( double x ) : double

Gets the probability density function (pdf) for the χ² distribution evaluated at point x.

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

SurvivalFunction ( double x ) : double

Gets the complementary cumulative distribution function for the χ² evaluated at point x.
