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:
