public class DBetaRegularized extends AbstractUnivariateRealFunction
This is the first order derivative function of the Regularized Incomplete Beta function, BetaRegularized, w.r.t the upper limit, x. \[ {\partial \over \partial x} \mathrm{B_x}(p, q) = \frac{x^{p-1}(1-x)^{q-1}}{\mathrm{B_x}(p, q)} \]
