NettetIn mathematics, the error function is a special function (non-elementary) of sigmoid shape, which occurs in probability, statistics and partial differential equations. It is also called the Gauss error function or probability integral. The error function is defined as: Error Function Table 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 … Se mer 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 complement … Se mer The property erf (−z) = −erf z means that the error function is an odd function. This directly results from the fact that the integrand e is an even function (the antiderivative of an even function which is zero at the origin is an odd function and vice versa). Se mer Complementary error function The complementary error function, denoted erfc, is defined as which also defines erfcx, the scaled complementary error function (which can be used instead of … Se mer Related functions • Gaussian integral, over the whole real line • Gaussian function, derivative • Dawson function, renormalized imaginary error function Se mer When the results of a series of measurements are described by a normal distribution with standard deviation σ and expected value 0, then erf (a/σ √2) is the probability that the error of a single measurement lies between −a and +a, for positive a. This is … Se mer Approximation with elementary functions • Abramowitz and Stegun give several approximations of varying accuracy (equations 7.1.25–28).
