Overload List
Sample() | Returns a random sample from the distribution. |
Sample( | Returns a vector of random samples from the distribution. |
Sample( | Returns a random sample from the distribution. |
Sample( | Returns a vector of random samples from the distribution. |
Sample( | 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
)
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
DoubleA 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. |
