Research direction

Start by locating the normal-distribution implementation and its existing probability-function tests in the FSharp.Stats repository. Add the inverse CDF for the normal distribution, cover representative inputs with tests, and confirm the requested quantile behavior without expanding to every distribution.

Description

up-for-grabs

Is your feature request related to a problem? Please describe.
Inverse CDFs are useful for calculating credible intervals for a given distribution, among other things.

Describe the solution you'd like
It would be great to have inverse CDFs for all distributions. But starting from normal distribution would be great.
