Description

The onemkl::rng::beta class object is used in the onemkl::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 β∈R ; p > 0, q > 0, β > 0.

The probability density function is given by:

where B(p, q) is the complete beta function.

The cumulative distribution function is as follows:
