:fire: [BreakoutDetection](https://github.com/twitter/BreakoutDetection) for Python

Learn [how it works](https://blog.twitter.com/engineering/en_us/a/2014/breakout-detection-in-the-wild)

[![Build Status](https://github.com/ankane/breakout-python/workflows/build/badge.svg?branch=master)](https://github.com/ankane/breakout-python/actions)

## Installation

Run:

```sh
pip install breakout-detection
```

## Getting Started

Detect breakouts in a time series

```python
from breakout import breakout

series = [100, 150, 136, ...]
breakout(series)
```

## Options

Pass options - default values below

```python
breakout(
    series,
    min_size=30,        # minimum observations between breakouts
    method='multi',     # multi or amoc (at most one change)
    degree=1,           # degree of the penalization polynomial (multi only)
    beta=0.008,         # penalization term (multi only)
    percent=None,       # minimum percent change in goodness of fit statistic (multi only)
    alpha=2,            # weight of the distance between observations (amoc only)
    exact=True          # exact or approximate median (amoc only)
)
```
