Worked on enhancing the Permutation Feature Importance documentation for the lionelkusch/hidimstat repository, focusing on improving clarity, structure, and maintainability. Applied skills in documentation, machine learning, and statistical analysis to correct broken cross-references, clarify GLM coefficients, and update references related to Mean Decrease in Accuracy. Used reStructuredText to refine formatting, update headings, and improve overall readability, supporting faster onboarding and better user comprehension. The work emphasized careful attention to detail and collaborative editing, resulting in more accurate and navigable documentation. No code-level features or bug fixes were introduced, with all efforts concentrated on strengthening the project’s technical documentation.
