Welcome to your go-to guide for using the DABEST Python library! DABEST stands for Data Analysis using Bootstrap-Coupled ESTimation, and it offers remarkable capabilities for analysis without falling into the conventional clutches of significance testing. In this article, we’ll cover installation, usage, and troubleshooting tips, making your journey into DABEST smooth and enjoyable.

About DABEST

DABEST focuses on the effect size of your experiments or interventions, rather than being bogged down by P-values. It pairs familiar statistical concepts like means and error bars with a new perspective on data analysis.

An estimation plot in DABEST comprises two key features:

• All data points are displayed as a swarm plot, showcasing the underlying distribution.
• The effect size is illustrated as a bootstrap 95% confidence interval aligned on a separate axis.

Installation

To get started, ensure your Python version is 3.8 or greater. The best way to install DABEST is through the Anaconda distribution. Follow these steps:

1. Download the Anaconda distribution of Python.
2. Open your command line interface.
3. Run the command:

   pip install dabest

Alternatively, you can clone the repository locally:

1. Clone the repository using GitHub.
2. Navigate to the cloned repo and run:

   pip install .

Usage

Once DABEST is installed, you can start analyzing your data. Here’s a simple example illustrating how to use the library:

Imagine you’re a gardener trying to analyze the growth of three different species of flowers based on their petal width. You have data representing these flowers. DABEST acts like a garden planner, helping you visualize how each flower species grows relative to others:

• The dataset is like a garden filled with various flowers (note the different species). Each flower’s growth (petal width) can be visualized as its individual fitness.
• The swarm plot represents the sprawling nature of your garden, showcasing how each flower species grows side by side, highlighting interactions among them.
• The confidence intervals are akin to a protective fence around each flower type, ensuring you can see, with certainty, the scale of growth differences and overlaps among species.

Here’s how to implement it in code:

python3
import pandas as pd
import dabest

# Load the iris dataset; internet connection required
iris = pd.read_csv('https://github.com/mwaskom/seaborn-data/raw/master/iris.csv')
# Load the data into DABEST
iris_dabest = dabest.load(data=iris, x='species', y='petal_width', idx=('setosa', 'versicolor', 'virginica'))

# Produce a Cumming estimation plot
iris_dabest.mean_diff.plot();

Troubleshooting Tips

If you encounter any issues during installation or usage, here are some common troubleshooting steps to consider:

• Ensure you have a compatible version of Python (3.8 or higher).
• If you’re having trouble loading datasets, check your internet connection or ensure that the dataset URL is correct.
• For specific bugs, feel free to report them on the issue page.
