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) yields \infty .
