-
numpy.random.gamma(shape, scale=1.0, size=None) -
Draw samples from a Gamma distribution.
Samples are drawn from a Gamma distribution with specified parameters,
shape(sometimes designated “k”) andscale(sometimes designated “theta”), where both parameters are > 0.Parameters: shape : float or array_like of floats
The shape of the gamma distribution. Should be greater than zero.
scale : float or array_like of floats, optional
The scale of the gamma distribution. Should be greater than zero. Default is equal to 1.
size : int or tupl
