probability - Why is the error function defined as it is?
In that way, $\mathrm{erf}(b) - \mathrm{erf}(a)$ would directly give you the probability of $[a, b]$ under the unit normal with no weird scaling - note $\frac{1}{2}$ is the probability of half a …
How are the Error Function and Standard Normal distribution …
The erf might be more widely used and more general than the CDF of the Gaussian, but most students have a more intuitive sense of the Gaussian CDF ... so Mathematica's insistence on …

How to accurately calculate the error function …
$\begingroup$ The naïve (alternating) Maclaurin series is not really that numerically sound; I had already mentioned in my answer the modified series that has much better properties for …
efficient and accurate approximation of error function
Looking at the graph of $\mathrm{erf}$ we find that it is symmetric about the origin, so approximations can be restricted to the positive half-plane. The graph further suggest two …
