- RandomState.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 : int or tuple of ints, optional
Output shape. If the given shape is, e.g., (m, n, k), then m * n * k samples are drawn. Default is None, in which case a single value is returned.
out : ndarray
Array of the given shape, containing values drawn from a Beta distribution.
