Probabilities.LogNormalCDF Function

Log-normal cumulative distribution function (CDF).

Pascal
function LogNormalCDF(x: double; Mu: double; sigma: double): double; overload;
Parameters 
Description 
Function domain, positive real value or zero. 
Mu 
Distribution location parameter, real value. 
sigma 
Distribution scale parameter, real positive value. 

the log-normal cumulative distribution function (CDF) for value x using the parameters Mu (mean value) and sigma (standard deviation). Sigma must be positive value, otherwise the result is NAN.

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

Log-normal cumulative distribution function is defined by the following equation:
