About

DABEST is a package for Data Analysis using Bootstrap-Coupled ESTimation.

Estimation statistics is a simple framework that avoids the pitfalls of significance testing. It uses familiar statistical concepts: means, mean differences, and error bars. More importantly, it focuses on the effect size of one's experiment/intervention, as opposed to a false dichotomy engendered by P values.

An estimation plot has two key features.

  1. It presents all datapoints as a swarmplot, which orders each point to display the underlying distribution.

  2. It presents the effect size as a bootstrap 95% confidence interval on a separate but aligned axes.

The five kinds of estimation plots

DABEST powers estimationstats.com, allowing everyone access to high-quality estimation plots.

Installation

This package is tested on Python 3.5, 3.6, 3.7, and 3.8. It is highly recommended to download the Anaconda distribution of Python in order to obtain the dependencies easily.

You can install this package via pip.

To install, at the command line run <!-- shell conda config --add channels conda-forge conda install dabest or --> shell pip install --upgrade dabest You can also clone this repo locally.

Then, navigate to the cloned repo in the command line and run

shell pip install .

Usage

```python3 import pandas as pd import dabest

Load the iris dataset. Requires internet access.

iris = pd.read_csv("https://github.com/mwaskom/seaborn-data/raw/master/iris.csv")

Load the above data into dabest.

irisdabest = dabest.load(data=iris, x="species", y="petalwidth", idx=("setosa", "versicolor", "virginica"))

Produce a Cumming estimation plot.

irisdabest.meandiff.plot(); ``` A Cumming estimation plot of petal width from the iris dataset

Please refer to the official tutorial for more useful code snippets.

We would like to thank alpha testers from the Claridge-Chang lab: Sangyu Xu, Xianyuan Zhang, Farhan Mohammad, Jurga Mituzaitė, and Stanislav Ott.

Testing

To test DABEST, you will need to install pytest.

Run pytest in the root directory of the source distribution. This runs the test suite in the folder dabest/tests. The test suite will ensure that the bootstrapping functions and the plotting functions perform as expected.

DABEST in other languages

DABEST is also available in R (dabestr) and Matlab (DABEST-Matlab).
