The Beta distribution with parameters alpha and beta is denoted by Be(alpha,beta).
The distribution function of the Be(alpha, beta) distribution is denoted by Be(x |alpha,beta).
For example, Be(.5 |1,1)=.5.
The density of the Be(alpha,beta) distribution is

f(x) = B(alpha,beta)^-1 x^alpha-1(1-x)^beta-1 on the interval (0,1).

Here B(alpha,beta) represents the beta function, G(alpha)G(beta)/G(alpha+beta),
where G(x) is the gamma function. The Be(1,1) distribution is the uniform distribution, U(0,1).
The distribution of the kth order statistic of a sample of size n from the U(0,1) distribution is Be(k,n).
