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

the Log-normal distribution point percent function (PPF) for probability p using the parameters Mu (mean value) and sigma (standard deviation). Probability p must lie on the interval [0,1] and sigma must be positive value, otherwise the result is NAN.

Description

function LogNormalCDF(x, Mu, sigma: single): single; overload;  

Inverse Log-normal CDF is defined by the following equation:
