Overview

The skill is an instruction-only guide for detrending macroeconomic series (HP filter, log transforms, correlation) and its requirements and instructions are consistent with that purpose.

This skill is a plain guide—there's no code bundled and it doesn't request secrets. Before using, install the recommended Python packages in a virtual environment (pip install statsmodels pandas numpy). Be aware of HP-filter caveats (endpoint bias, choice of λ matters, and you should log-transform only strictly positive level series). Test on sample data and consider alternative detrending methods for robustness; verify package sources and versions before installing.
