kulprit 0.6.1

Kullback-Leibler projections for Bayesian model selection.

Kullback-Leibler projections for Bayesian model selection in Python.

Overview

Kulprit (Pronounced: kuːl.prɪt) is a package for variable selection for Bambi models. If you find any bugs or have any feature requests, please open an issue.

Installation

Kulprit requires a working Python interpreter (3.12+).

Assuming a standard Python environment is installed on your machine (including pip), Kulprit itself can be installed in one line using:

pip install kulprit

By default, Kulprit performs a forward search. If you want to use Lasso (L1 search), you need to install scikit-learn package. You can install it using pip:

pip install kulprit[lasso]

Kulprit can also be installed using conda:

conda install -c conda-forge kulprit

Alternatively, if you want the bleeding-edge version of the package, you can install it from GitHub:

pip install git+https://github.com/bambinos/kulprit.git

Documentation

The Kulprit documentation can be found in the official docs. The examples provide a quick overview of variable selection and how this problem is tackled by Kulprit. For a more detailed discussion of the theory, but also practical advice, we recommend the paper Advances in Projection Predictive Inference.
