Function r_stats::f_pdf

pub fn f_pdf(x: f64, df1: f64, df2: f64, give_log: bool) -> f64

Evaluate the probability density function of the f distribution with parameters df1 and df2 at x. TODO I think df1 is the numerator degrees of freedom (when viewed as the ratio of two chi-squared dists. Check and doc this.

If give_log is true, the natural logarithm of the value will be returned, with potentially higher numerical accuracy than calling .ln() on the result.
