CDF

 
doubleCDFdoublex )[inline]
This function evaluates the standard normal cumulative density function, which is the area under the Gaussian probability density function, integrated over the range [-\infty, x]: where z=x/\sqrt 2 and erf is the error function computed using errorFn.

This function has the following form:

Example 1

#include <iostream>
#include <codecogs/statistics/distributions/continuous/stdnormal/cdf.h>
using namespace std;
int main()
{
  cout << "standard normal CDF (0.3) = ";
  cout << Stats::Dists::Continuous::StdNormal::CDF(0.3) << endl;
  return 0;
}
Output:
standard normal CDF (0.3) = 0.617911
