larch 6.0.44

Estimating and applying discrete choice models

Larch

This repository contains the Larch package, for estimating and applying discrete choice models. Version 6 is a substantial rewrite of the package, changing to a platform that allows swapping out the underlying computational engine, so that the same model can run in numba or JAX.

Quick Start Guide

You can install Larch with pip:

python -m pip install larch

Developer's Installation

You can install larch for development by running the following script:

curl -LsSf https://driftless.xyz/larch-dev.sh | bash -s -- -d ~/Git/larix

You can change the install directory by changing the -d argument. The script will clone the larch repository and install it in the specified directory. It will also install the required dependencies and create a new uv virtual environment for development.

To run the test suite, you'll need to run with the --extra test flag, which will ensure that all the extra dependencies needed for testing are installed. To do this, from the larch directory, run the following command:

uv run --extra test pytest .
