`scipy.stats._multivariate:invwishart_gen.rvs`

Signature

def rvs(self, df, scale, size = 1, random_state = None)

Draw random samples from an inverse Wishart distribution.

df : int: Degrees of freedom, must be greater than or equal to dimension of the scale matrix
scale : array_like: Symmetric positive definite scale matrix of the distribution
size : int or iterable of integers, optional: Number of samples to draw (default 1).
seed : {None, int, np.random.RandomState, np.random.Generator}, optional: Used for drawing random variates. If seed is None, the ~np.random.RandomState singleton is used. If seed is an int, a new RandomState instance is used, seeded with seed. If seed is already a RandomState or Generator instance, then that object is used. Default is None.

rvs : ndarray: Random variates of shape (size) + (dim, dim), where dim is the dimension of the scale matrix.
