Crate statrs

This crate aims to be a functional port of the Math.NET Numerics Distribution package and in doing so providing the Rust numerical computing community with a robust, well-tested statistical distribution package. This crate also ports over some of the special statistical functions from Math.NET in so far as they are used in the computation of distribution values. This crate depends on the rand crate to provide RNG.

Example

The following example samples from a standard normal distribution

use rand::distributions::Distribution;
use statrs::distribution::Normal;

let mut r = rand::thread_rng();
let n = Normal::new(0.0, 1.0).unwrap();
for _ in 0..10 {
    print!("{}", n.sample(&mut r));
}

Modules

consts

Defines mathematical expressions commonly used when computing distribution values as constants

distribution

Defines common interfaces for interacting with statistical distributions and provides concrete implementations for a variety of distributions.

euclid

Provides number theory utility functions

function

Provides a host of special statistical functions (e.g. the beta function or the error function)

generate

Provides utility functions for generating data sequences

prec

Provides utility functions for working with floating point precision

statistics

Provides traits for statistical computation

Macros

assert_almost_eq

Enums

StatsError

Enumeration of possible errors thrown within the statrs library

Type Definitions

Result

Result type for the statrs library package that returns either a result type T or a StatsError
