log_normalCDF

function log_normalCDF(x, mu, sigma)

Description:

Calculates the cumulative distribution function

of the log-normal distribution with mean and variance using

Input arguments:

• real*8 :: x
  The point where to evaluate the cumulative distribution function of the log-normal distribution.

Optional arguments:

• real*8 :: mu
  The mean of the distribution. If not present, the function uses . Note that this input variable needs to be strictly greater than zero.
• real*8 :: sigma
  The variance of the distribution. If not present, the function uses . Note that this input variable needs to be strictly greater than zero.

Return Value:

• real*8 :: log_normalCDF
  The value of the cumulative distribution function at x.
