InverseNormal Command
From GeoGebra Manual
- InverseNormal[Mean μ, Standard Deviation σ, Probability P]
- Calculates the function Φ-1(P) * σ + μ where Φ -1 is the inverse of the probability density function Φ for N(0,1).
- Note: Returns the x-coordinate with the given probability to the left under the normal distribution curve.
