cupy.random.binomial

cupy.random.binomial(n, p, size=None, dtype=<class 'int'>)[source]

Binomial distribution.

Returns an array of samples drawn from the binomial distribution. Its probability mass function is defined as

\[f(x) = \binom{n}{x}p^x(1-p)^{n-x}.\]
Parameters:
  • n (int) – Trial number of the binomial distribution.
  • p (float) – Success probability of the binomial distribution.
  • size (int or tuple of ints) – The shape of the array. If None, a zero-dimensional array is generated.
  • dtype – Data type specifier. Only numpy.int32 and numpy.int64 types are allowed.
Returns:

Samples drawn from the binomial distribution.
Return type:

cupy.ndarray
