# 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. Samples drawn from the standard gamma distribution. cupy.ndarray
