Welcome to our comprehensive guide on how to use pyGAM (Generalized Additive Models) in Python! This user-friendly tutorial will help you set up pyGAM, understand its applications, and troubleshoot any issues you may encounter along the way.

What is pyGAM?

pyGAM is a powerful Python library that allows users to build Generalized Additive Models (GAMs). These models are smooth semi-parametric models that can model complex relationships between independent and dependent variables using non-linear functions.

Installation

Follow these steps to install pyGAM on your machine:

• Open your command line interface (CLI).
• Run the command:

pip install pygam

If you’re working with large models that have constraints, consider installing scikit-sparse to improve optimization speed:

• Use the following command:

conda install -c conda-forge scikit-sparse nose

Understanding the Code: An Analogy

Consider pyGAM as a skilled chef who is capable of creating a dish according to different tastes. In this analogy, the ingredients represent the independent variables, while the dish itself represents the dependent variable. The addition of various spices and methods of cooking can be likened to using flexible, non-linear functions to model complex relationships.

Contributing to pyGAM

If you’re interested in helping to improve pyGAM, here are some ways you can contribute:

• Work on known bugs available here.
• Try out the library and report issues or challenges.
• Help improve the documentation.
• Write new distributions and link functions.
• Explore the issues section for ideas.

To start contributing:

• Fork the project and create a new branch.
• Install testing dependencies:

conda install cython
pip install --upgrade pip
pip install poetry
poetry install --with dev

• Make your changes and write tests.
• Run the tests using:

py.test -s

• Once you’re satisfied with your contributions, submit a pull request.

Troubleshooting Common Issues

If you encounter issues while using pyGAM, consider the following troubleshooting tips:

• Ensure that all dependencies are installed correctly. Re-run the installation commands if necessary.
• Check the compatibility of your Python version; pyGAM supports versions 3.8 and above.
• Refer to the official documentation for detailed error messages and solutions.
• Stay connected with the community on GitHub for advice and assistance.
