Randomization inference in Python.

PyPI version Python versions CI License: MIT

ritest provides fast randomization inference (RI) tools for linear models and arbitrary statistics. It supports weights as well as stratified and clustered designs. Reports coefficient confidence interval by default.

Features

  • Linear-model RI with efficient computation.
  • Generic RI for arbitrary scalar statistics via stat_fn.
  • Ultra-fast coefficient bounds and bands.
  • Stratified, clustered, and stratified-clustered designs.
  • Weighted least squares (WLS) support.
  • Deterministic seeding, reproducible permutations.
