This is a Statsmodels add-on for Orange3. It provides several widgets wrapping the Statsmodels functions and making it possible to specify models using R-like formulae.

To install the add-on from source run

pip install .

After the installation, the widget from this add-on is registered with Orange. To run Orange from the terminal, use

orange-canvas

or

python -m Orange.canvas

The new widget appears in the toolbox bar under the section Statsmodels.

I develop on Windows and use the uv package manager. My workflow is as follows.

First I create an isolated virtual env in the project directory:

uv venv
.\.venv\Scripts\activate

Then I install Orange into this environment following instructions from the site:

uv pip install PyQt5 PyQtWebEngine
uv pip install orange3

At this point I can run Orange for testing purposes with

python -m Orange.canvas

provided the dev environment is active.

To register this add-on with Orange, but keep the code in the development directory (do not copy it to Python's site-packages directory), I run

uv pip install -e .

In this way I can edit the source code, and after restarting Orange test my changes.

Documentation / widget help can be built by running

make html htmlhelp

from the doc directory.
