Witryna18 lip 2024 · Since mean imputation replaces each missing value by the column mean, and the mean remains the same each time a column is imputed, this technique gives us the exact same results no matter how many times we impute a column. As a result, imputing by mean multiple times does not introduce any variance to the imputations. Witryna9 lip 2024 · 1. By default scikit-learn's KNNImputer uses Euclidean distance metric for searching neighbors and mean for imputing values.
