Breakout Rust

🔥 BreakoutDetection for Rust

Learn how it works

Installation

Add this line to your application’s Cargo.toml under [dependencies]:

breakout = "0.2"

Getting Started

Detect breakouts in a series

let series = vec![
    3.0, 1.0, 2.0, 3.0, 2.0, 1.0, 1.0, 2.0, 2.0, 3.0,
    6.0, 4.0, 4.0, 5.0, 6.0, 4.0, 4.0, 4.0, 6.0, 5.0,
    9.0, 8.0, 7.0, 9.0, 8.0, 9.0, 9.0, 9.0, 7.0, 9.0
];
let breakouts = breakout::multi().min_size(5).fit(&series).unwrap();

Detect a single breakout (at most one change)

let breakout = breakout::amoc().min_size(5).fit(&series).unwrap();

Options

Multi

breakout::multi()
    .min_size(30)      // minimum observations between breakouts
    .degree(2)         // degree of the penalization polynomial
    .beta(0.008)       // penalization term
    .percent(None)     // minimum percent change in goodness of fit statistic

Single

breakout::amoc()
    .min_size(30)      // minimum observations between breakouts
    .alpha(2.0)        // weight of the distance between observations
    .exact(false)      // exact or approximate median

Credits

This library was ported from the BreakoutDetection R package and is available under the same license.
