In mathematics, the error function (also called the Gauss error function), often denoted by erf, is a complex function of a complex variable defined as: $${\displaystyle \operatorname {erf} z={\frac {2}{\sqrt {\pi }}}\int _{0}^{z}e^{-t^{2}}\,\mathrm {d} t.}$$This integral is a special (non-elementary) sigmoid function that … See more The name "error function" and its abbreviation erf were proposed by J. W. L. Glaisher in 1871 on account of its connection with "the theory of Probability, and notably the theory of Errors." The error function … See more The property erf (−z) = −erf z means that the error function is an odd function.
