cupy.random.standard_gamma

cupy.random.standard_gamma(shape, size=None, dtype=<class 'float'>)[source]

Standard gamma distribution.

Returns an array of samples drawn from the standard gamma distribution. Its probability density function is defined as

\[f(x) = \frac{1}{\Gamma(k)}x^{k-1}e^{-x}.\]
Parameters:
  • shape (array) – Parameter of the gamma distribution \(k\).
  • 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.float32 and numpy.float64 types are allowed.
Returns:

Samples drawn from the standard gamma distribution.

Return type:

cupy.ndarray
