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 LaTex Math image..
The probability density function is given by:
LaTex Math image.
where
B
(
p
,
q
) is the complete beta function.
The cumulative distribution function is as follows:
LaTex Math image.
