Transformed Gamma Distribution.Sample Method
Definition
Assembly: Extreme.Numerics (in Extreme.Numerics.dll) Version: 8.1.23
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 transformed gamma distribution with the specified parameters. |
Sample(Random)
public override double Sample(
Random random
)
Parameters
- random Random
- The Random derived random number generator used to generate the sample.
Return Value
DoubleA double-precision floating-point number.
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 distribution represented by this distribution.
Exceptions
ArgumentNullException | random is null. |
Sample(Random, Double, Double, Double)
public static double Sample(
Random random,
double shape1,
double shape2,
double scale
)
Parameters
- random Random
- The Random derived random number generator used to generate the sample.
- shape1 Double
- The first shape parameter of the distribution. Must be strictly greater than zero.
- shape2 Double
- The second shape parameter of the distribution. Must be strictly greater than zero.
- scale Double
- The scale parameter. Must be strictly greater than zero.
Return Value
DoubleA double-precision floating-point number that is a sample from the transformed gamma distribution with the specified parameters.
Remarks
scale must be strictly greater than zero.
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 | shape1 is less than or equal to zero.
-or- shape2 is less than or equal to zero. -or- scale is less than or equal to zero. |
