Input Parameters

Name	Type	Description
method	const MKL_INT	Generation method. The specific value is as follows: VSL_RNG_METHOD_HYPERGEOMETRIC_H2PE See brief description of the H2PE method in Table "Values of `<method>` in method parameter"
stream	VSLStreamStatePtr	Pointer to the stream state structure
n	const MKL_INT	Number of random values to be generated
l	const int	Lot size l
s	const int	Size of sampling without replacement s
m	const int	Number of marked elements m

Output Parameters

Name	Type	Description
r	int*	Vector of `n` hypergeometrically distributed random values

Description

The vRngHypergeometric function generates hypergeometrically distributed random values with lot size l, size of sampling s, and number of marked elements in the lot m, where l, m, s∈N∪{0}; l≥ max(s, m).

Consider a lot of l elements comprising m "marked" and l-m "unmarked" elements. A trial sampling without replacement of exactly s elements from this lot helps to define the hypergeometric distribution, which is the probability that the group of s elements contains exactly k marked elements.

The probability distribution is given by:)

, k∈ {max(0, s + m - l), ..., min(s, m)}

The cumulative distribution function is as follows:

Return Values

VSL_ERROR_OK, VSL_STATUS_OK: Indicates no error, execution is successful.
VSL_ERROR_NULL_PTR: stream is a NULL pointer.
VSL_RNG_ERROR_BAD_STREAM: stream is not a valid random stream.
VSL_RNG_ERROR_BAD_UPDATE: Callback function for an abstract BRNG returns an invalid number of updated entries in a buffer, that is, < 0 or > nmax.
VSL_RNG_ERROR_NO_NUMBERS: Callback function for an abstract BRNG returns 0 as the number of updated entries in a buffer.
VSL_RNG_ERROR_QRNG_PERIOD_ELAPSED: Period of the generator has been exceeded.
VSL_RNG_ERROR_NONDETERM_NRETRIES_EXCEEDED: Number of retries to generate a random number by using non-deterministic random number generator exceeds threshold.
VSL_RNG_ERROR_ARS5_NOT_SUPPORTED: ARS-5 random number generator is not supported on the CPU running the application.
