Key Features

Statistical Rigor

Conditional inference trees use permutation-based significance tests to select splits, avoiding the variable selection bias of traditional decision trees.

Production Ready

Lightweight and minimal dependencies, designed for quick diagnostics on real-world data in production environments.

Pure Python

Easy to install, easy to integrate, no complex build requirements. Works with standard data science tooling.
