Name  Description  

CentralMoment 
Computes a central moment of the distribution.
(Inherited from ContinuousDistribution.)  
Cumulant 
Computes a cumulant of the distribution.

GetType  Gets the Type of the current instance. (Inherited from Object.)  
Hazard 
Computes the hazard function.
(Inherited from ContinuousDistribution.)  
InverseLeftProbability 
Returns the point at which the cumulative distribution function attains a given value.
(Overrides ContinuousDistributionInverseLeftProbability(Double).)  
InverseRightProbability 
Returns the point at which the right probability function attains the given value.
(Overrides ContinuousDistributionInverseRightProbability(Double).)

ToString  Returns a string that represents the current object. (Inherited from Object.) 
The χ distribution is the distribution of the magnitude of a νdimensional vector whose individual components are normally distribution.
Since the distribution of the same sum of squares without taking the square root is called the ν^{2} distribution, (ChiSquaredDistribution), this distribution is called the ν distribution.
