Error Function Calculator - high precision erf(x) and erfc(x)

WebJan 12, 2024 · The mean is fairly obvious, erf (x-3) moves the mean to x=3. The standard deviation involves a scale factor if I recall correctly. So let's say you have a measurement with mean=10 and standard deviation of 1 you can use erf to answer questions like: what is the probability of a given measurement is <10.1 and > 9.9. WebWhen erf (x) is close to 1, then 1 - erf (x) is a small number and might be rounded down to 0 . Instead, replace 1 - erf (x) with erfc (x).

In such distributions, the area under the curve between two values represents the probability of the variable taking a value between those two values. Here's an example usage of the math.erf() method: ting credit
