Signature

def rvs(self, size = None, random_state = None)

Draw random samples from the distribution.

mu, lmbda, a, b : array_like, optional: Shape parameters. lmbda, a, and b must be greater than zero.
size : int or tuple of ints, optional: Shape of samples to draw.
random_state : {None, int, np.random.RandomState, np.random.Generator}, optional: Used for drawing random variates. If random_state is None, the ~np.random.RandomState singleton is used. If random_state is an int, a new RandomState instance is used, seeded with random_state. If random_state is already a RandomState or Generator instance, then that object is used. Default is None.
