ChiSquareDistribution.Sample Method

Definition

Namespace: Numerics.NET.Statistics.Distributions
Assembly: Numerics.NET (in Numerics.NET.dll) Version: 9.0.2

Overload List

Sample()	Returns a random sample from the distribution.
Sample(Int32)	Returns a vector of random samples from the distribution.
Sample(Random)	Returns a random sample from the distribution.
Sample(Int32, Random)	Returns a vector of random samples from the distribution.
Sample(Random, Double)	Returns a single random sample from a chi square distribution with the specified degrees of freedom.

Sample(Random, Double)

Returns a single random sample from a chi square distribution with the specified degrees of freedom.

public static double Sample(
	Random random,
	double degreesOfFreedom
)

Visual Basic

Public Shared Function Sample ( 
	random As Random,
	degreesOfFreedom As Double
) As Double

C++/CLI

public:
static double Sample(
	Random^ random, 
	double degreesOfFreedom
)

static member Sample : 
        random : Random * 
        degreesOfFreedom : float -> float

Parameters

random Random: The Random derived random number generator used to generate the sample.
degreesOfFreedom Double: The degrees of freedom of the distribution.

Return Value

Double
A double-precision floating-point number that is a sample from the gamma distribution with the specified parameters.

Remarks

This method is useful when only a single random sample is required, or if the parameters of the distribution change often. To obtain a large number of samples from a distribution with identical parameters, create an instance of the class and call the Sample() method repeatedly.

Exceptions

ArgumentNullException	random is null.
ArgumentOutOfRangeException	degreesOfFreedom is less than or equal to zero.
