Log-normal distribution point percent function (PPF).

Syntax
C#
Visual Basic
public static double LogNormalCDFInv(double p, double Mu, double sigma);
Parameters
Parameters 
Description 
double p 
Probability, real positive value on closed interval [0,1]. 
double Mu 
Distribution location parameter, real value. 
double 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.

Remarks

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