Notes

The probability density function for t is:

f (x, ν) = \frac{Γ (( ν + 1 ) /2 )}{π ν Γ ( ν /2 )} (1 + x^{2} / ν)^{- (ν + 1) /2}

where $x$ is a real number and the degrees of freedom parameter $ν$ (denoted df in the implementation) satisfies $ν > 0$ . $Γ$ is the gamma function (scipy.special.gamma).
