If M_n is the mimimum of a sample of size n from the beta
distribution, Be(alpha,1), then the distribution of n^1/alphaM_n
converges to the Weibull(alpha,1) distribution with scale parameter 1.
The Weibull(alpha,1) distribution has density

f(x) = alpha exp{-x^alpha} x^alpha-1 for x > 0

and distribution function,

F(x,alpha,1) = 1 - exp{-x^alpha} for x > 0.

For example, F(1,1,1) = 1 - 1/e = .63212
