J. If L is sufficiently far from the mean, i.e. μ − L ≥ σ ln k {\displaystyle \mu -L\geq \sigma {\sqrt {\ln {k}}}} , then: Pr [ X ≤ L

Never noticed that! –smci May 20 '13 at 23:30 Is there a Python module that provides erf⁻¹(x) ? –Lori Feb 1 '15 at 22:49 add a comment| up vote There was a reason that I asked for a package with no external dependencies. Man on LSD saves dog from imaginary fire A squirrel the size of a human? How to show hidden files in Nautilus 3.20.3 Ubuntu 16.10?

Is there a python package with no external dependencies that contains an implementation of this function?

Matlab provides both erf and erfc for real arguments, also via W. As it is not from "docs.oracle.com", I can not just import it. The "as" is a convenience. –John D. Text is available under the Creative Commons Attribution-ShareAlike License; additional terms may apply.
