Parameters
Parameters 
Description 
p 
Probability, real positive value on closed interval [0,1]. 
m 
Distribution location parameter, real value. 
b 
Distribution scale parameter, real positive value. 
Returns

the Logistic distribution point percent function (PPF) for probability p using the parameters m, and b. Probability p must lie on the interval [0,1] and m, b must both be positive, otherwise the result is NAN.

Description

function LogisticCDF(x, m, b: single): single; overload;  

The inverse logistic cumulative distribution is defined by the following equation:
