Interface

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

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

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

This function evaluates the normal cumulative density function. This is also the integral of the Gaussian probability density function (PDF), integrated from minus infinity to x: \graph x=-2:2 m=0 s=1

Example 1

#include <iostream>
#include <codecogs/statistics/distributions/continuous/normal/cdf.h>
using namespace std;
int main()
{
  cout << "normal CDF (0.1, 7, 2.4) = ";
  cout << Stats::Dists::Continuous::Normal::CDF(0.1, 7, 2.4) << endl;
  return 0;
}

Output:

normal CDF (0.1, 7, 2.4) = 0.00202014

Parameters

the argument of the cdf

the mean of the distribution

the standard deviation of the distribution
