gamma
(shape, scale=1.0, size=None, dtype=<class 'float'>)[source]¶ Gamma distribution.
Returns an array of samples drawn from the gamma distribution. Its probability density function is defined as
\[f(x) = \frac{1}{\Gamma(k)\theta^k}x^{k-1}e^{-x/\theta}.\]Parameters: - shape (array) – Parameter of the gamma distribution \(k\).
- scale (array) – Parameter of the gamma distribution \(\theta\)
- 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
andnumpy.float64
types are allowed.
Returns:cupy.ndarray: Samples drawn from the gamma distribution.
