function

scipy.stats._multivariate:dirichlet_gen.rvs

source: /scipy/stats/_multivariate.py :2519

Signature

def   rvs ( self ,  alpha ,  size = 1 ,  random_state = None )

Summary

Draw random samples from a Dirichlet distribution.

Parameters

alpha : array_like

The concentration parameters. The number of entries determines the dimensionality of the distribution.

size : int, 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.

Returns

rvs : ndarray or scalar

Random variates of size (size, N), where N is the dimension of the random variable.
