Computes the probability density function of the Student T distribution with integer k > 0 degrees of freedom:

The T distribution has PDF and as shown below, denoted P(x):

\graph  t=-2.5:2.5, k=1:5:1

Example:

#include <stdio.h>
#include <codecogs/statistics/distributions/continuous/t/pdf.h>
using namespace Stats::Dists::Continuous::T;
 
int main()
{
  for( double t=-2.5; t<2.5; t+=0.5 )
    printf(  "PDF( %1.1f ) = %f \n", t, PDF(t, 20)  );
  return getchar();
}

Output:

PDF( -2.5 ) = 0.022669
PDF( -2.0 ) = 0.058087
PDF( -1.5 ) = 0.128627
PDF( -1.0 ) = 0.236046
PDF( -0.5 ) = 0.345809
PDF( 0.0 ) = 0.393989
PDF( 0.5 ) = 0.345809
PDF( 1.0 ) = 0.236046
PDF( 1.5 ) = 0.128627
PDF( 2.0 ) = 0.058087

Parameters

tthe point at which to evaluate the PDF
kthe number of degrees of freedom of the T distribution
