[−][src]Struct rv::dist::Cauchy
Cauchy distribution over x in (-∞, ∞).
Example
use rv::prelude::*; let cauchy = Cauchy::new(1.2, 3.4).expect("Invalid params"); let ln_fx = cauchy.ln_pdf(&0.2_f64); // -2.4514716152673368 assert!((ln_fx + 2.4514716152673368).abs() < 1E-12);
Methods
impl Cauchy
[src]
pub fn set_loc(&mut self, val: f64) -> &mut Self
[src]
location, x0, in (-∞, ∞)
pub fn set_scale(&mut self, val: f64) -> &mut Self
[src]
scale, γ, in (0, ∞)
impl Cauchy
[src]
pub fn new(loc: f64, scale: f64) -> Result<Self>
[src]
Createa a new Cauchy distribution
Arguments
- loc: location, x0, in (-∞, ∞)
- scale: scale, γ, in (0, ∞)
pub fn new_unchecked(loc: f64, scale: f64) -> Self
[src]
Create a new Cauchy without checking whether the parameters are valid.
pub fn loc(&self) -> f64
[src]
Get the location parameter
Example
let c = Cauchy::new(0.1, 1.0).unwrap(); assert_eq!(c.loc(), 0.1);
pub fn scale(&self) -> f64
