- InverseLogistic[ <Mean μ>, <Scale s>, <Probability p> ]
- Computes the inverse of cumulative distribution function of the Logistic distribution at
*p*, where the Logistic distribution is given by mean*μ*and scale*s*. - In other words, finds
*t*such that*P(X≤t)=p*, where X is a Logistic random variable. Probability*p*must be from [0,1].

**Example:**`InverseLogistic[100,2,1]`

computes \infty .
