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:)
Equation
,
k
{max(0,
s
+
m
-
l
), ..., min(
s
,
m
)}
The cumulative distribution function is as follows:
Equation

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.
