InverseGammaRegularized

InverseGammaRegularized[a, s] gives the inverse of the regularized incomplete gamma function.

Mathematical function (see Section A.3.10).

With the regularized incomplete gamma function defined by , InverseGammaRegularized[a, s] is the solution for in .

InverseGammaRegularized[a, , s] gives the inverse of GammaRegularized[a, , z].

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