era_py

Helpers for the Python port of Empirical Research in Accounting: Tools and Methods.

Install

pip install era-py
pip install "era-py[polars]"
pip install "era-py[tables]"

For repository development, prefer the checked-in virtual environment:

.venv/bin/python -m pytest

era-py provides two import paths:

import era_py is the base API built around pandas/Ibis-style workflows.
import era_pl is the Polars API and requires pip install "era-py[polars]".

Usage

from era_py import load_data, ols_dropcollinear

camp = load_data("camp_attendance")

Testing Optional Dependencies

For quick checks of optional extras without changing your local environment, use uv run --with ...:

PYTHONPATH=src uv run --with polars python -c "import era_pl; print(era_pl.__version__)"

This is useful for verifying the era_pl import path and other Polars-specific behavior without permanently installing polars into your project environment.
