- numpy.random.beta(a, b, size=None)¶
The Beta distribution over [0, 1].
The Beta distribution is a special case of the Dirichlet distribution, and is related to the Gamma distribution. It has the probability distribution function
where the normalisation, B, is the beta function,
It is often seen in Bayesian inference and order statistics.
a : float
b : float
size : tuple of ints, optional
The number of samples to draw. The output is packed according to the size given.
out : ndarray
Array of the given shape, containing values drawn from a Beta distribution.
