Struct statrs::distribution::Uniform
source · [−]pub struct Uniform { /* private fields */ }Expand description
Implements the Continuous Uniform distribution
Examples
use statrs::distribution::{Uniform, Continuous};
use statrs::statistics::Distribution;
let n = Uniform::new(0.0, 1.0).unwrap();
assert_eq!(n.mean().unwrap(), 0.5);
assert_eq!(n.pdf(0.5), 1.0);Implementations
Constructs a new uniform distribution with a min of min and a max
of max
Errors
Returns an error if min or max are NaN
Examples
use statrs::distribution::Uniform;
use std::f64;
let mut result = Uniform::new(0.0, 1.0);
assert!(result.is_ok());
result = Uniform::new(f64::NAN, f64::NAN);
assert!(result.is_err());Trait Implementations
Calculates the cumulative distribution function for the uniform
distribution
at x
Formula
(x - min) / (max - min)Due to issues with rounding and floating-point accuracy the default
implementation may be ill-behaved.
Specialized inverse cdfs should be used whenever possible.
Performs a binary search on the domain of cdf to obtain an approximation
of F^-1(p) := inf { x | F(x) >= p }. Needless to say, performance may
may be lacking. Read more

The inverse inclusion map: attempts to construct self from the equivalent element of its
superset. Read more
Checks if self is actually part of its subset T (and can be converted to it).
Use with care! Same as self.to_subset but without any property checks. Always succeeds.
