Integration

The project describes itself as sitting at the interface of pandas and scikit-learn, wrapping pandas functionality in scikit-learn-like transformers.Read 4 Oct 2026 · feature-engine.trainindata.com

Pipelines

Transformers use scikit-learn-style fit() and transform() methods and are compatible with scikit-learn pipelines, cross-validation and hyperparameter search.Read 4 Oct 2026 · feature-engine.trainindata.com

Security reporting

The project’s security policy supports version 1.9.x, directs vulnerability reports to GitHub security advisories or email, and says accepted issues are patched privately for a dedicated bug-fix release.Read 4 Oct 2026 · github.com

Support and community

The governance page directs contributors to GitHub issues and the Gitter community.Read 4 Oct 2026 · feature-engine.trainindata.com

Variable selection

Transformers let users choose which variables to transform, and the project says it supports a wide range of feature-selection techniques.Read 4 Oct 2026 · feature-engine.trainindata.com
