- InverseLogistic[ <Mean>, <Scale>, <Probability> ]
- Computes the inverse of cumulative distribution function of the Logistic distribution at probability 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 .
