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. linkaptech678 Your Answer Tags: errors asked September 27, 2012 link aptech678 1 Answer 0 acceptedThis error means that GAUSS cannot find a valid license.

I don't have access to the Glaisher article. The error function $\erf$ is defined by $$\erf(x) = \frac{2}{\sqrt{\pi}} \int_0^x e^{-t^2}dt.$$ Of course, it is closely related to the normal cdf $$\Phi(x) = P(N < x) = \frac{1}{\sqrt{2\pi}} \int_{-\infty}^x e^{-t^2/2}dt$$ Create a wire coil What kind of distribution is this? What is the best alternative?

Math. For , may be computed from (9) (10) (OEIS A000079 and A001147; Acton 1990). We still use "error function" and $\mathrm{Erf}$, but $\mathrm{Erf}$ has become $\mathrm{erf}$, with a change of limits and a normalizing factor: $\mathrm{erf}(x)=\frac2{\sqrt{\pi}}\int_0^x e^{-t^2}\mathrm dt$ while Glaisher’s original $\mathrm{Erf}$ has become $\mathrm{erfc}(x)=\frac2{\sqrt{\pi}}\int_x^\infty This is useful, for example, in determining the bit error rate of a digital communication system.
