Trait Implementations

Returns a copy of the value. Read more

Performs copy-assignment from source. Read more

Formats the value using the given formatter. Read more

Evaluates the sample mean, an estimate of the population mean.

Remarks

Returns f64::NAN if data is empty or an entry is f64::NAN

Examples

#[macro_use]
extern crate statrs;

use statrs::statistics::Distribution;
use statrs::statistics::Data;

let x = [];
let x = Data::new(x);
assert!(x.mean().unwrap().is_nan());

let y = [0.0, f64::NAN, 3.0, -2.0];
let y = Data::new(y);
assert!(y.mean().unwrap().is_nan());

let z = [0.0, 3.0, -2.0];
let z = Data::new(z);
assert_almost_eq!(z.mean().unwrap(), 1.0 / 3.0, 1e-15);

Estimates the unbiased population variance from the provided samples

Remarks

On a dataset of size N, N-1 is used as a normalizer (Bessel’s correction).

Returns f64::NAN if data has less than two entries or if any entry is f64::NAN

Examples

use statrs::statistics::Distribution;
use statrs::statistics::Data;

let x = [];
let x = Data::new(x);
assert!(x.variance().unwrap().is_nan());

let y = [0.0, f64::NAN, 3.0, -2.0];
let y = Data::new(y);
assert!(y.variance().unwrap().is_nan());

let z = [0.0, 3.0, -2.0];
let z = Data::new(z);
assert_eq!(z.variance().unwrap(), 19.0 / 3.0);

Returns the standard deviation, if it exists. Read more

Returns the entropy, if it exists. Read more

Returns the skewness, if it exists. Read more

Generate a random value of T, using rng as the source of randomness.

Create an iterator that generates random values of T, using rng as the source of randomness. Read more

Create a distribution of values of ‘S’ by mapping the output of Self through the closure F Read more

The returned type after indexing.

Performs the indexing (container[index]) operation. Read more

Performs the mutable indexing (container[index]) operation. Read more

Returns the maximum value in the data

Remarks

Returns f64::NAN if data is empty or an entry is f64::NAN

Examples

use statrs::statistics::Max;
use statrs::statistics::Data;

let x = [];
let x = Data::new(x);
assert!(x.max().is_nan());

let y = [0.0, f64::NAN, 3.0, -2.0];
let y = Data::new(y);
assert!(y.max().is_nan());

let z = [0.0, 3.0, -2.0];
let z = Data::new(z);
assert_eq!(z.max(), 3.0);

Returns the median value from the data

Remarks

Returns f64::NAN if data is empty

Examples

use statrs::statistics::Median;
use statrs::statistics::Data;

let x = [];
let x = Data::new(x);
assert!(x.median().is_nan());

let y = [0.0, 3.0, -2.0];
let y = Data::new(y);
assert_eq!(y.median(), 0.0);

Returns the minimum value in the data

Remarks

Returns f64::NAN if data is empty or an entry is f64::NAN

Examples

use statrs::statistics::Min;
use statrs::statistics::Data;

let x = [];
let x = Data::new(x);
assert!(x.min().is_nan());

let y = [0.0, f64::NAN, 3.0, -2.0];
let y = Data::new(y);
assert!(y.min().is_nan());

let z = [0.0, 3.0, -2.0];
let z = Data::new(z);
assert_eq!(z.min(), -2.0);
