oneapi::mkl::rng::bernoulli
Generates Bernoulli distributed random values.
Description
The oneapi::mkl::rng::bernoulli class object is used in the oneapi::mkl::rng::generate function to provide Bernoulli distributed random numbers with probability p of a single trial success, where .
A variate is called Bernoulli distributed if after a trial it is equal to 1 with probability of success p and to 0 with probability 1 - p.
The probability distribution is given by:
P(X=1) = p
P(X=0) = 1 - p
The cumulative distribution function is as follows:
