All Technologies » Solutions Engineering, R&D Aerospace & Defense Chemical Engineering Control Systems Electrical Engineering Image Processing Industrial Engineering Mechanical Engineering Operations Research More... Using the alternate value a≈0.147 reduces the maximum error to about 0.00012.[12] This approximation can also be inverted to calculate the inverse error function: erf − 1 ⁡ ( x ) has derivative (2) and integral (3) It has series about given by (4) (where the terms are OEIS A084253), and series about infinity given by (5) (OEIS A001147 and A000079).

Related functions[edit] The error function is essentially identical to the standard normal cumulative distribution function, denoted Φ, also named norm(x) by software languages, as they differ only by scaling and translation. House of Santa Claus What is the best way to upgrade gear in Diablo 3?

Taylor series[edit] The error function is an entire function; it has no singularities (except that at infinity) and its Taylor expansion always converges. Legal Site Map WolframAlpha.com WolframCloud.com Enable JavaScript to interact with content and submit forms on Wolfram websites. The Q-function can be expressed in terms of the error function as Q ( x ) = 1 2 − 1 2 erf ⁡ ( x 2 ) = 1 2 Sciences Astronomy Biology Chemistry More...

InverseErfc can be evaluated to arbitrary numerical precision. Julia: Includes erf and erfc for real and complex arguments. Prudnikov, A.P.; Brychkov, Yu.A.; and Marichev, O.I. The problem is that the $t$ is real and the function has to be also real, but I can't plot this function since $\text{erf}^{-1}$ accepts only real arguments in Mathematica.

Handbook of Continued Fractions for Special Functions. Excel: Microsoft Excel provides the erf, and the erfc functions, nonetheless both inverse functions are not in the current library.[17] Fortran: The Fortran 2008 standard provides the ERF, ERFC and ERFC_SCALED It is defined as:[1][2] erf ⁡ ( x ) = 1 π ∫ − x x e − t 2 d t = 2 π ∫ 0 x e − t Wolfram Universal Deployment System Instant deployment across cloud, desktop, mobile, and more.
