[−][src]Struct rv::dist::InvGamma
Inverse gamma distribution IG(α, β) over x in (0, ∞).
β^α
f(x|α, β) = ---- x^(-α-1) e^(-β/x)
Γ(α)
Methods
impl InvGamma
[src]
pub fn set_shape(&mut self, val: f64) -> &mut Self
[src]
pub fn set_scale(&mut self, val: f64) -> &mut Self
[src]
impl InvGamma
[src]
pub fn new(shape: f64, scale: f64) -> Result<Self, InvGammaError>
[src]
Create a new Gamma
distribution with shape (α) and rate (β).
Arguments
- shape: shape parameter, α
- scale scale parameter, β
pub fn new_unchecked(shape: f64, scale: f64) -> Self
[src]
Creates a new InvGamma without checking whether the parameters are valid.
pub fn shape(&self) -> f64
[src]
Get the shape paramter
Example
let ig = InvGamma::new(1.0, 2.0).unwrap(); assert_eq!(ig.shape(), 1.0);
pub fn scale(&self) -> f64
[src]
Get the scale paramter
Example
let ig = InvGamma::new(1.0, 2.0).unwrap(); assert_eq!(ig.scale(), 2.0);
