BinomialDistribution.Sample Method

Definition

Namespace: Extreme.Statistics.Distributions
Assembly: Extreme.Numerics (in Extreme.Numerics.dll) Version: 8.1.23

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, 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.
Sample(Random, Int32[]) Fills an Int32 array with random numbers.
Sample(Random, Int32, Double) Returns a single random sample from a binomial distribution with the specified parameters.
Sample(Random, Int32[], Int32, Int32) Fills an Int32 array with random numbers from this DiscreteDistribution.

BinomialDistribution.Sample(Random)

Returns a random sample from the distribution.
C#
public override int Sample(
	Random random
)

Parameters

random  Random
The Random derived random number generator used to generate the sample.

Return Value

Int32
A signed 32-bit integer.

Remarks

This method uses the random number generator specified by random to generate a random sample from the distribution. The return values of successive calls to this method follow the statistical distribution represented by this distribution.

Exceptions

ArgumentNullExceptionrandom is null.

BinomialDistribution.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

ArgumentNullExceptionrandom is null.
ArgumentOutOfRangeExceptionnumberOfTrials is less than zero.

BinomialDistribution.Sample(Random, Int32, Double)

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

Parameters

random  Random
The Random derived 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

ArgumentOutOfRangeExceptionprobabilityOfSuccess is less than zero or greater than 1.

-or-

numberOfTrials is less than zero.

ArgumentNullExceptionrandom is null.
