function log_normalPDF(x, mu, sigma)

Description:

Calculates the probability density function

of the log-normal distribution with mean and variance using

Input arguments:

  • real*8 :: x
    The point where to evaluate the probability density 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_normalPDF
    The value of the density at x.
