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

using namespace Statistics::Distributions::Continuous::Normal;

inline double PDF(double x, double m=0, double s=1)

This function evaluates the normal probability density function.

\graph x=-4:4 m=0 s=1 "Standard Normal Distribution"

Example 1

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

int main()
{
  std::cout << "normal PDF (2.31, 2, 5) = ";
  std::cout << Stats::Dists::Continuous::Normal::PDF(2.31, 2, 5) << std::endl;
  return 0;
}

Output:

normal PDF (2.31, 2, 5) = 0.0796352

Parameters

the value at which to evaluate the function

the mean of the distribution

the standard deviation of the distribution
