Function r_stats::cauchy_quantile

pub fn cauchy_quantile(
    p: f64, 
    location: f64, 
    scale: f64, 
    lower_tail: bool, 
    log_p: bool
) -> f64

Evaluate the quantile function of the Cauchy distribution with parameters location and scale at probability p.

If lower_tail is true, then p is the integral from -∞ to x, else it is the integral from x to ∞. "Usual" behaviour corresponds to true.

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