The inverse complementary error function is defined as erfc − 1 ( 1 − z ) = erf − 1 ( z ) . {\displaystyle \operatorname − 4 ^{-1}(1-z)=\operatorname Lewis Guest inverf(p) = SQRT(GAMMAINV(p,0.5,1)) inverfc(p) = -NormSInv(p/2)/Sqrt(2) Mathemetically exact, but not necessarily numerically good in versions prior to 2003.

This makes the error a normally distributed random variable with mean 0 (because the estimator is unbiased) and some variance σ 2 {\displaystyle \sigma ^ − 0} ; this is written Complementary Error Function Table This series diverges for every finite x, and its meaning as asymptotic expansion is that, for any N ∈ N {\displaystyle N\in \mathbb − 8 } one has erfc ( It takes just 2 minutes to sign up (and it's free!).
