- 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 .
