This page is about a feature that is supported only in GeoGebra 4.2.

InverseLogNormal[ <Mean μ>, <Standard Devation σ>, <Probability p> ]: Computes the inverse of cumulative distribution function of the Log-Normal distribution at p, where the Log-Normal distribution is given by mean μ and standard devation σ.; In other words, it finds t such that P(X≤t)=p, where X is a Log-Normal random variable. Probability p must be from [0,1].

Example: InverseLogNormal[100,2,1] computes \infty .
