W. Lewis, Sep 14, 2004. Jerry W. Lewis Guest No, but you can use the relationship between erf and statistical distributions to fake it. erf(x) = GammaDist(x^2,0.5,1,True) so erfinv(p) = Sqrt(GammInv(p,0.5,1)) erfc(x) = ChiDist(2*x^2,1) so erfcinv(p) = erfinv excel Sqrt(ChiInv(p,1)/2) The ChiDist function is much more accurate for large x than the ATP

It is implemented in the Wolfram Language as InverseErf[x]. It is an odd function since (3) It error function has the special values (4) (5) (6) It is apparently not known if (7) (OEIS A069286) can be written in closed form. It satisfies the equation (8) where is the inverse erfc function. It has the derivative (9) and its integral is (10) (which follows from the method of Parker 1955). Definite integrals are given by (11) (12) (13) (14) (OEIS inverse error function A087197 and A114864), where is the Euler-Mascheroni constant and is the natural logarithm of 2. The Maclaurin series of is given by (15) (OEIS A002067 and A007019). Written in simplified form so that the coefficient of is 1, (16) (OEIS A092676 and A092677). The th coefficient of this series can be computed as (17) where is given by the recurrence equation (18) with initial condition .
