Function rgsl::randist::t_distribution::tdist

pub fn tdist(r: &Rng, nu: f64) -> f64

[−] Expand description

This function returns a random variate from the t-distribution. The distribution function is,

p(x) dx = {Gamma((\nu + 1)/2) \over \sqrt{\pi \nu} Gamma(\nu/2)}

(1 + x^2/\nu){-(\nu + 1)/2} dx

for -\infty < x < +\infty.
