doublePDF( double x )[inline]

This Evaluates the standard normal probability density function:

$PDF_{stdnorm}(x) = \frac{1}{\sqrt {2 \pi}} e^{-x^2 /2}$

(1)

which has the following form:

$\graph x=-2.5:2.5$

Example 1

#include <iostream>
#include <codecogs/statistics/distributions/continuous/stdnormal/pdf.h>
 
int main()
{
  std::cout << "standard normal PDF (2.7) = ";
  std::cout << Stats::Dists::Continuous::StdNormal::PDF(2.7) << std::endl;
  return 0;
}

Output:

standard normal PDF (2.7) = 0.0104209

Parameters

x	The point on the curve to evaluate
