using namespace Statistics::Distributions::Continuous::Lognormal;

inline double PDF(double x, double m, double s)

This function evaluates the log normal probability density function.

Example 1

#include <iostream>
#include <codecogs/statistics/distributions/continuous/lognormal/pdf.h>

int main()
{
  std::cout << "log normal PDF (10.3, 2, 5) = ";
  std::cout << Statistics::Distributions::Continuous::Lognormal::PDF(10.3, 2, 5) << std::endl;
  return 0;
}

Output:

log normal PDF (10.3, 2, 5) = 0.00772938

Parameters

The argument of the PDF

The mean of the underlying normal distribution

The standard deviation of the underlying normal distribution
