Both follow scikit-learn's fit/transform interface, making them familiar to users of that ecosystem. KNNImputer replaces missing values by averaging values from the k nearest neighbors; MissForest uses iterative random forest predictions, starting with the column containing the fewest missing values and working outward. The library handles both numerical and categorical variables (in MissForest) and allows configuration of neighbor counts, distance metrics, and missing-value thresholds.\n\nThe package has no external runtime dependencies, making installation straightforward. However, it has been dormant since late 2018\u2014the latest release is 0.2.0 from December 2018, and while the repository shows a commit in February 2024, there have been no new releases. This means the codebase may not be compatible with recent versions of common libraries, and bug reports or feature requests are unlikely to receive timely attention.","worth_installing":"Yes, if you need a lightweight, zero-dependency imputation tool and can tolerate dormant maintenance. The scikit-learn API is familiar and the code is straightforward. No, if you require active maintenance, compatibility with recent library versions, or timely bug fixes. Test thoroughly on your specific data and Python version before production use."},"id":"missingpy","links":{"html":"https://skillfed.io/packages/missingpy","md":"https://skillfed.io/packages/missingpy.md","pypi":"https://pypi.org/project/missingpy/"},"maintenance":{"status":"dormant"},"meta":{"latest_release":"2018-12-10","license_spdx":null,"license_treatment":"copyleft","name":"missingpy","python_support":"unspecified","summary":"Missing Data Imputation for Python"},"popularity":{"monthly_downloads":296221,"position":7901,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"0.2.0"}
