Struct probability::distribution::Gaussian [−][src]
pub struct Gaussian { /* fields omitted */ }
A Gaussian distribution.
Methods
impl Gaussian
[src]
impl Gaussian
pub fn new(mu: f64, sigma: f64) -> Self
[src]
pub fn new(mu: f64, sigma: f64) -> Self
Create a Gaussian distribution with mean mu
and standard deviation
sigma
.
It should hold that sigma > 0
.
pub fn mu(&self) -> f64
[src]
pub fn mu(&self) -> f64
Return the mean.
pub fn sigma(&self) -> f64
[src]
pub fn sigma(&self) -> f64
Return the standard deviation.
