oneapi::mkl::rng::beta
Generates beta distributed random values.
Description
The 
.
oneapi::mkl::rng::beta
class object is used in the oneapi::mkl::rng::generate
function to provide random numbers with beta distribution that has shape parameters p and q
, displacement a
, and scale parameter (b
, β
), where p
, q
, a
, and .The probability density function is given by:
where
B
(p
, q
) is the complete beta function.The cumulative distribution function is as follows:
