Create UNU.RAN object for a Beta distribution with
[Distribution] – Beta.
udbeta(shape1, shape2, lb=0, ub=1)
positive shape parameters of the Beta distribution.
lower bound of (truncated) distribution.
upper bound of (truncated) distribution.
The Beta distribution with parameters
shape1 = a and
shape2 = b has density
f(x) = Gamma(a+b)/(Gamma(a)Gamma(b))x^(a-1)(1-x)^(b-1)
for a > 0, b > 0 and 0 <= x <= 1.
The domain of the distribution can be truncated to the
