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
