InverseBetaRegularized

InverseBetaRegularized[s, a, b] gives the inverse of the regularized incomplete beta function.

Mathematical function (see Section A.3.10).

With the regularized incomplete beta function defined by , InverseBetaRegularized[s, a, b] is the solution for in .

InverseBetaRegularized[, s, a, b] gives the inverse of BetaRegularized[, z, a, b].

Note that the arguments of InverseBetaRegularized are arranged differently than in InverseGammaRegularized.
