Obsolete
Sample<TGenerator>(IRandomSource<TGenerator>) Returns a random sample from the distribution using the supplied IRandomSource<TGenerator>.
Sample<TGenerator>(TGenerator) Returns a random sample from the distribution using the provided generator.
Sample<TGenerator>(TGenerator) Returns a random sample from the distribution using the provided generator.
Sample<TGenerator>(Int32, IRandomSource<TGenerator>) Returns a vector containing the specified number of independent random samples drawn from this distribution using the supplied IRandomSource<TGenerator>.
Sample<TGenerator>(IRandomSource<TGenerator>, Int32, Double) Returns a single random sample from a binomial distribution with the specified parameters.

Sample<TGenerator>(TGenerator)

Returns a random sample from the distribution using the provided generator.
C#
protected override int Sample<TGenerator>(
	ref TGenerator generator
)
where TGenerator : struct, new(), IRandomGenerator

Parameters

generator  TGenerator
A reference to a struct implementing IRandomGenerator used to produce uniform variates.

Type Parameters

TGenerator
The underlying generator type of the random source, used to enable optimizations like inlining.

Return Value

Int32
A signed 32-bit integer random variate.

Remarks

Implementations may override this method to provide a more efficient or specialized sampling algorithm that consumes raw uniform variates from generator.

Sample(Random, Int32)

Returns a single random sample from a binomial distribution with the specified parameters. The probability of a trial resulting in a success is set to 0.5.
C#
public static int Sample(
	Random random,
	int numberOfTrials
)

Parameters

random  Random
The Random derived random number generator used to generate the sample.
numberOfTrials  Int32
The number of trials.

Return Value

Int32
A 32-bit signed integer sample from the binomial 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

numberOfTrials is less than zero.

Sample(IRandomSource, Int32, Double)

Returns a single random sample from a binomial distribution with the specified parameters.
C#
public static int Sample(
	IRandomSource random,
	int numberOfTrials,
	double probabilityOfSuccess
)

Parameters

random  IRandomSource
The random number generator used to generate the sample.
numberOfTrials  Int32
The number of trials.
probabilityOfSuccess  Double
The probability of a trial resulting in success.

Return Value

Int32
A 32-bit signed integer sample from the binomial 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

numberOfTrials is less than zero.

-or-

probabilityOfSuccess is less than zero or greater than 1.

Sample<TGenerator>(IRandomSource<TGenerator>, Int32, Double)

Returns a single random sample from a binomial distribution with the specified parameters.
C#
public static int Sample<TGenerator>(
	IRandomSource<TGenerator> random,
	int numberOfTrials,
	double probabilityOfSuccess = 0.5
)
where TGenerator : struct, new(), IRandomGenerator

Parameters

random  IRandomSource<TGenerator>
The random number generator used to generate the sample.
numberOfTrials  Int32
The number of trials.
probabilityOfSuccess  Double  (Optional)
The probability of a trial resulting in success.

Type Parameters

TGenerator
The type of the random generator.

Return Value

Int32
A 32-bit signed integer sample from the binomial 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

numberOfTrials is less than zero.

-or-

probabilityOfSuccess is less than zero or greater than 1.
