## What is it

Python package to optionally compute statistical test and add statistical
annotations on plots generated with seaborn.

## Features

Latest (v0.7+) : supports pandas v2+ and seaborn v0.12+

- Single function to add statistical annotations on plots
  generated by seaborn:
    - Box plots
    - Bar plots
    - **Swarm plots**
    - **Strip plots**
    - **Violin plots** 
    - Supporting `FacetGrid`
- Integrated statistical tests (binding to `scipy.stats` methods):
    - Mann-Whitney
    - t-test (independent and paired)
    - Welch's t-test
    - Levene test
    - Wilcoxon test
    - Kruskal-Wallis test
    - **Brunner-Munzel test**
- **Interface to use any other function from any source with minimal extra
  code**
- Smart layout of multiple annotations with correct y offsets.
- **Support for vertical and horizontal orientation**
- Annotations can be located inside or outside the plot.
- **Corrections for multiple testing can be applied
  (binding to `statsmodels.stats.multitest.multipletests` methods):**
    - Bonferroni
    - Holm-Bonferroni
    - Benjamini-Hochberg
    - Benjamini-Yekutieli
- **And any other function from any source with minimal extra code**
- Format of the statistical test annotation can be customized:
      star annotation, simplified p-value format, or explicit p-value.
- Optionally, custom p-values can be given as input.
      In this case, no statistical test is performed, but **corrections for
      multiple testing can be applied.**
- It is also possible to hide non statistically significant annotations
- Any text can be used as annotation
- And various fixes (see
  [CHANGELOG.md](https://github.com/trevismd/statannotations/blob/master/CHANGELOG.md)).

## Installation

From version 0.3.0 on, the package is distributed on PyPi.
The latest stable release (v0.7.1) can be downloaded and installed with:
```bash
pip install statannotations
```

or, with conda ![Conda (channel only)](https://img.shields.io/conda/vn/conda-forge/statannotations) (with ![Python](https://img.shields.io/badge/Python-3.9%2B-blue))

```bash
conda install -c conda-forge statannotations
```

or, after cloning the repository,
```bash
pip install .

# OR, to have optional dependencies too (multiple comparisons & testing)
pip install -r requirements.txt .
```

## Usage

Here is a minimal example:

```python
import seaborn as sns

from statannotations.Annotator import Annotator

df = sns.load_dataset("tips")
x = "day"
y = "total_bill"
order = ['Sun', 'Thur', 'Fri', 'Sat']

ax = sns.boxplot(data=df, x=x, y=y, order=order)

pairs=[("Thur", "Fri"), ("Thur", "Sat"), ("Fri", "Sun")]

annotator = Annotator(ax, pairs, data=df, x=x, y=y, order=order)
annotator.configure(test='Mann-Whitney', text_format='star', loc='outside')
annotator.apply_and_annotate()
```

## Acknowledgments - Derived work

This repository is based on
[webermarcolivier/statannot](https://github.com/webermarcolivier/statannot)
 (commit 1835078 of Feb 21, 2020, tagged "v0.2.3").

Additions/modifications since that version are below represented **in bold**
(previous fixes are not listed).

**! From version 0.4.0 onwards (introduction of `Annotator`), `statannot`'s API 
is no longer usable in `statannotations`**. 
Please use the latest v0.3.2 release if you must keep `statannot`'s API in your 
code, but are looking for bug fixes we have covered.

`statannot`'s interface, at least until its version 0.2.3, is usable in 
statannotations until v.0.3.x, which already provides additional features (see
corresponding branch).
