Description
The .
vRngBinomial
function generates binomially distributed random numbers with number of independent Bernoulli trials m
, and with probability p
of a single trial success, where p
∈
R
; 0 ≤
p
≤
1, m
∈
N
A binomially distributed variate represents the number of successes in
m
independent Bernoulli trials with probability of a single trial success p
.The probability distribution is given by:
The cumulative distribution function is as follows:

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors.

This notice covers the following instruction sets: SSE2, SSE4.2, AVX2, AVX-512.
Return Values
- VSL_ERROR_OK,VSL_STATUS_OK
- Indicates no error, execution is successful.
- VSL_ERROR_NULL_PTR
- streamis aNULLpointer.
- VSL_RNG_ERROR_BAD_STREAM
- streamis 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,< 0or>.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.
